From this list here. This was the best I could find when looking for a list of  "classic" Japanese songs. English sources that talk about J-pop mostly focus on idols or anime songs. The list is a bit outdated, but it covers a good variety of genres.

50. Pearl Jam - Better Man

49. Florence + the Machine - Dog Days Are Over
Considering how classic rock these countdowns tend to be, I really didn't expect this.

48. The Strokes - Last Nite

47. The Offspring - Self Esteem

46. Nick Cave & The Bad Seeds - Into My Arms
Oh no, I forgot about this song!

45. Modest Mouse - Float On
I downloaded Good News... and for some reason this song wasn't in the zip, so I didn't hear it for ages.

44. Daft Punk - One More Time

43. John Butler Trio - Betterman

42. Matt Corby - Brother
I don't think this belongs here. I don't think it's a bad song, but there are probably a hundred songs better than it.

41. Coldplay - Yellow
I'm really glad Coldplay exists now. It seems to be the one thing that both pop music and indie rock types can enjoy/tolerate, judging from how the uni music club always ends up singing one of their songs at the end of gatherings.

40. Nine Inch Nails - Closer
My IB45 friend was into romance novels, so I read one with her so we'd have something to talk about. In the book, the heroine would nearly faint every time she heard this song because it reminded her of her ex. And that's how I first heard this great song.

39. Nirvana - Heart Shaped Box
Thumbs up for this song. Ooh, the Spotify playlist updates in real time.

38. The Temper Trap - Sweet Disposition
Having seen this band at the ARIAs, I can confirm that the singer can goddamn sing.

37. Beastie Boys - Sabotage

36. Jeff Buckley - Hallelujah
Whoa, expected this to be higher. I could live without hearing any version of this song again though, it's good but overplayed to death.

35. Radiohead - Karma Police
Cool. I remember a friend showing me how to play this on guitar. Paranoid Android better be up there somewhere.

34. Ben Folds Five - Brick
Didn't expect this. I guess this is the song that made Ben Folds decide to focus on sappier sort of songs, but I do like it.

33. The Cranberries - Zombie
The chord progression sounds a bit like Coldplay's "The Scientist", doesn't it? But this came first. People just love songs that go "eh eh eh oh". It's pretty fun to sing to.

32. Tool - Stinkfist
Oh, so this is Tool. Interesting. Another album atarred on Spotify for later listening.

31. Massive Attack - Teardrop
Here's another song I considered voting for. Thank you, House MD.

30. RHCP - Californication
Only listened to this album because of how much I heard about its terrible mastering. It really was exhausting to listen to. This song is okay/meh, though I'd probably hate it if I were born a bit earlier.

29. Franz Ferdinand - Take Me Out
Ridiculously catchy guitar riff.

28. RHCP - Scar Tissue
See above RHCP words. Oh yeah, I remember living in Brisbane and being on a train full of crazy excited people going to their concert. Ah, Ipswich line.

27. The Avalanches - Frontier Psychiatrist
Finally, another song I voted for! It would have been embarrassing for everyone if the only one I got right(!?) was Lana Del Rey.

26. System Of A Down - Chop Suey
I'm not at all familiar with this.

25. Smashing Pumpkins - Bullet With Butterfly Wings
Didn't vote for this song, but happy it's here.

24. Augie March - One Crowded Hour
Hooray, another vote in. Probably the only #1 I really like. Awesome lyrics.

23. Muse - Knights of Cydonia
This song is hilarious. I wouldn't say that I like Muse ironically, but I don't really think they're great either. Their songs are just really fun to sing to and play on Guitar Hero. Just sitting around quietly listening to them? Nah.

22. Blur - Song 2
Woo hoo. (But I like the Parklife stuff more...)

21. Smashing Pumpkins - 1979
Hmm, I probably should have voted for this.

20. The Living End - Prisoner Of Society
Didn't expect this so high. I remember the teachers at my high school singing this at the graduation of the cohort above ours. For my year, they did Green Day, and it was nowhere near as fun.

19. Blink-182 - Dammit
I don't really like this band. I was never into pop punk or emo.

18. Outkast - Hey Ya
What!? Thought it'd be top 10. This is a nice break from all of those rock songs.

17. Silverchair - Tomorrow
*shrug* I thought this was supposed to be a youth radio station.

16. Bon Iver - Skinny Love
Can't be surprised, considering how popular that Birdy cover became. I feel like the only person who doesn't think Justin Vernon's voice is beautiful, but his songs still manage to be pretty.

15. The Prodigy - Breathe
Heard this a lot but didn't what it was called.

14. Mumford & Sons - Little Lion Man
The best thing about this band is how people get entertainingly angry about them. I feel the same way about this as Angus & Julia Stone: hilarious in hindsight. (This really does not belong here though.)

13. Radiohead - Paranoid Android
Should be higher, but whatever. Gosh, what's going to be in the top ten then?

12. Gotye - Hearts A Mess
Surprising. I think I like this a bit more than STIUTK, probably because it's a lot less overplayed.

11. QOTSA - No One Knows
Wasn't really paying attention because I was eating, but I heard a nice guitar bit.

10. Powderfinger - My Happiness
Nostalgia votes, I guess. Haha, someone on Spotify just added it to their terrible early 2000s nostalgia playlist ("listen @ own risk").

9. Gotye - Somebody That I Used To Know
Thank you to my vocal group for showing me the intricacies of this song, as well as giving it some future sentimental value. I also remember it playing at my Yr 12 formal.

8. Powderfinger - These Days
I don't know this one, so no nostalgia for me. Bernard Fanning seems nice enough though.

7. The Killers - Mr Brightside
I actually think this song has the potential to grow on me a little more.

6. Foo Fighters - Everlong
I've... actually never heard this song. At least, I don't remember it

5. The Verve - Bitter Sweet Symphony
Here's another one of my votes. Thank God I like something that a lot of other people like. It's not actually one of my top 20 songs from the last two decades, but I wanted to vote for things that had a chance.

4. Hilltop Hoods - The Nosebleed Section
Probably the best of Australian hip hop, but I don't think that's saying much. The little explanation about the sample was interesting though.

3. Jeff Buckley - Last Goodbye
That's some impressive falsetto. Seven Nation Army and Wonderwall next?

2. The White Stripes - Seven Nation Army
Yep. Some kid at school suggested this to be our school song, with the seven nations representing the six IB groups and the hub. The guitar riff is basically this whole song.

1. Oasis - Wonderwall
I don't like Oasis. I only have to know this song for things like music club singalongs. That kind of thing is probably why so many people voted for it.

My votes are over here. How long will I last before I switch over to the Classic 100?

100. Beastie Boys - Intergalactic
We're off to a good start, though I guess all of the good stuff will be in the bottom half of the countdown, as always.

99. Lana Del Rey - Video Games
I didn't actually expect this to make it. I figured that to everyone else, this would be just another terrible buzz single. Overall, her catalogue is awful, but this one song is good. (So much Twitter butthurt.)

98. Jebediah - Leaving Home
Not familiar with this, though the I know the band is Australian. Meh.

97. MIA - Paper Planes
This should probably be higher, but okay.

96. The Cat Empire - Hello
Hmm. Definitely not better than Paper Planes. This looks like it's going to be a "Best of Triple J-Core" countdown.

95. Ben Lee - Cigarettes Will Kill You
There's a Ben I particularly dislike, it's either this guy or Ben Kweller. Definitely not Ben Folds, but all three are probably similar. Oh, this is the "Catch My Disease" one? Alright, this is my least favourite Ben.

94. Foster The People - Pumped Up Kicks
Catchy but insubstantial fluff. Sorry to my friends who love this band.

93. Soundgarden - Black Hole Sun
I was going to vote for either this or Smashing Pumpkins' "Today". If "Today" doesn't make it, I'll probably wish that I gave a vote to this song.

92. Of Monsters & Men - Little Talks
Are you fucking serious? Meanwhile, Philip Glass is on the Classic 100, so over there I go for now.

91. Jebediah - Harpoon

90. Silverchair - Straight Lines
Glass is finished, so I'm back. This song has a tiny bit of nostalgia value for me, but I don't really like it. It's a bit Coldplayish? I can see why people love it though.

89. TV On The Radio - Wolf Like Me
This band has been on my to-listen list for years, but I never got around to it. This seems like the kind of thing I'd be into.

88. Something For Kate - Monsters
Okay, nothing special, meh, etc.

87. The Kooks - Naive
Boring.

86. The Killers - When You Were Young
I like this in an indifferent, 6/10 sort of way.

85. Coolio - Gangsta's Paradise
Shit, I'm too young for this. This has nice production.

84. Kanye West - Gold Digger
This is really fun, but I think most of it is because of that sample.

83. Pulp - Common People
Ah, another song I wanted to vote for. This song is about middle-class people wanting to go ooh-ah at poor people, right? It's great.

82. Wheatus - Teenage Dirtbag
I guess this counts as a pop classic now. I think it's annoying, but it could be worse.

81. Angus & Julia Stone - Big Jet Plane
Oh my God, the nostalgia. People were so angry about this song! And my high school music teacher suggested them to me when I said most Australian music was boring...

80. Rage Against The Machine - Bulls On Parade
Missed most of this because I went to do the laundry.

79. Arctic Monkeys - I Bet You Look Good On The Dancefloor
My father likes this band.

78. Silverchair - Freak
I don't see anything really memorable about this song.

77. The Presents - My People
What's the difference between a good song and a song you heard a lot when you were young? It's really hard to tell. Apparently this song is about asylum seekers, and that's pretty cool.

76. MGMT - Electric Feel
I think there's a Foster The People song that sounds exactly like this!

75. The Killers - Somebody Told Me
Eh, I liked the other Killers song more. I didn't have any interest in music until 2009, and I've found that it's really hard to like anything I heard a lot before then.

74. The Wombats - Let's Dance To Joy Division
The disco noises and children's chorus make me cringe. Also, I feel like a horrible person because I seem to hate everything that my friends like.

73. Edward Sharpe & The Magnetic Zeros - Home
Hey, it's the original version of "Little Talks". There's something likable about it despite being one of those stupid "hey ho" songs.

72. Wolfmother - Joker & The Thief
All these old songs make me feel like I'm listening to that station that says, "the best mix of the 80s, 90s, and now!"

71. Gorillaz - Clint Eastwood
Whoops, zoned out.

70. Regurgitator - ! (The Song Formerly Known As)
69. Eminem - Lose Yourself
Nope, I'm not old enough for this.

68. Jet - Are You Gonna Be My Girl?
All of the celebration about their breakup made me really embarrassed for Australia.

67. Alt-J - Breezeblocks
Liked this song the first few times I heard it, but it got tiring. And 67 is waaaay to high.

66. You Am I - Berlin Chair
I couldn't decide which You Am I song I wanted to vote for. I'm glad this is here, even though I probably wouldn't consider it one of the best 100 songs of the last 20 years. But hey, this list was always going to be Australia-centric, and not really the best.

Right, I'm going to Hurstville. See you tomorrow.

Updated every 20 songs. Might graph the numbers afterwards.

100. Everything Everything - Cough Cough
Jesus, this was the worst feature album in recent memory. 3/10

99. MIA - Bad Girls
Hmm, fun, but could probably get annoying quickly. 6/10

98. Kimbra - Warrior (Ft. Mark Foster & A-Trak)
Bland. 4/10

97. Jack White - I'm Shakin'
7/10

96. Kanye West - Clique
Twitter has a lot of hate for Kanye. Bet the same people will be happy when Macklemore wins. Production sounds pretty good (as with everything Kanye is involved in). 8/10

95. Last Dinosaurs - Andy
Facebook friend voted for 3 songs by this band. They sure can play the guitar, but that production smothers the whole album into a samey mess. 5/10

94. The Gaslight Anthem - 45
Generic rock song. Annoying lyrics. 3/10

93. Snakadaktal - Dance Bear
I guess it's better than "Air". 6/10

92. Lisa Mitchell - Spiritus
IN MY LUMALUMALUM! Her voice has become so much more annoying. I suppose people encourage that horrid accent because it makes her "unique". 4/10

91. Allday x C1 - So Good
Don't know why, but it's reminding me of Kitty Pryde. 4/10

Compare with last year's chart here. Won't bother talking about what I talked about there.

Triple J Hottest 100

You voted for: 

David Byrne & St Vincent - Who 

Dirty Projectors - Gun Has No Trigger 

Bat For Lashes - Laura 

Beach House - Myth 

Cloud Nothings - Stay Useless 

Courtney Barnett - History Eraser 

Fiona Apple - Every Single Night 

Grimes - Oblivion 

Tame Impala - Feels Like We Only Go Backwards 

Catcall - The World Is Ours

I try to vote for things that are already listed, because they actually have a chance of making it in the countdown. The only one I added was Catcall. Here are the betting odds. Not a Macklemore fan, but it had better beat that awful Of Monsters & Men song.

The next time I get a lab placement, I'm going to TMS my brain until it fixes my musical preferences.

Clickety click. I guess Pitchfork got tired of people complaining that they don't provide opportunities for reader interaction, etc.

I'm looking through other lists, and I bet that a lot of reviews are going to get changed as a result of this poll. People seem to love Transatlanticism, which got a joke review! Lots of Dark Was The Night, which I personally didn't think was that good, but okay.

The homogeneity is a little disheartening. My list seems to be missing a lot of things that everybody else is including, e.g. Animal Collective, Spiritualized, The Microphones, and a few other things that got 10.0s, but I haven't heard them yet. Heck, I'm somewhat ashamed that I know which albums got the perfect score.

While making my list, I realized that a disproportionate amount of stuff I like is from before my time. Some people think it's cooler to like old music, but I feel that I should like things that are coming out now, just so I can later say, "Yeah, I totally remember when that came out." Isn't that even cooler than liking something that everyone has liked for ages? You have to think about the long term!

EDIT: I'm updating this as the situation changes. It's going to turn into a fun way to discover new music.

I know it's really stupid, but it's annoying to see posts on Facebook from distant acquaintances talking about something I like. Part of it is because I'm bitter about having no friends who like what I like. Another thing is that it's usually some vapid post like "[critically acclaimed album/artist] is awesome!" or some random lyrics, and then it gets a whole lot of likes and circlejerk comments. Karma whoring.

Well, screw that. I'm going to find alternatives that my news feed doesn't mention.

Prompted by /r/music, in no particular order. I know that I'm boring.

Talking Heads - Stop Making Sense
This might be the only album that I can listen to on repeat, in full.

Arcade Fire - Funeral
I remember when everybody was raving about The Suburbs, and I didn't get the hype for this band. Until I listened to this.

The National - Boxer
More vocalists should sound like Matt Berninger, and more bands should have a horn section. I like High Violet almost as much, but this one has the lyrics, "Sometimes you get up and bake a cake or something."

Pixies - Surfer Rosa
Doolittle is probably better, but I just can't listen to it any more.

Radiohead - In Rainbows
I am happy to know that it has become acceptable to like In Rainbows. If it's good enough for Steve Reich, it's good enough for me.

Sufjan Stevens - Age of Adz
I don't like electronics, and I don't like Jesus, but this album makes me want to reconsider my position on those things.

Wilco - Yankee Hotel Foxtrot
American, easier-to-digest Radiohead. That's a good thing.

You Am I - Hourly, Daily
Quote from some random on RYM: "If you have ever lived in Sydney, this album will go straight to your heart."

The Dismemberment Plan - Emergency & I
I love this because I can't buy it. Every physical format of it seems to be out of print. If I get stupidly rich, I will spend my wealth trying to find it.

Fiona Apple - When The Pawn...
Token female artist for my list, whoops. The only female singer who sings in my range, and "Get Gone" got me through senior year.

No Spotify, I don't have an Android phone.

Catcall - The Warmest Place
Not as great as what the Australian media said, but also not as bad as what Pitchfork said. I really like "Satellites".

Fiona Apple - The Idler Wheel...
I've already bought the CD, which says something about it! However, I can't help but think that the hype comes from the fact that her previous albums weren't given as much attention as they received.

Liars - WIXIW
Radiohead-ish. I didn't remember how any of it went after it finished, but I do remember enjoying it.

Jherek Bischoff - Composed
Orchestral pop with a few female vocalists. Nothing particularly exceptional, but I like this kind of thing.

The Cast of Cheers - Family
A Triple J feature album. Bloc Party meets summery indie pop. Very average.

Metric - Synthetica
Okay, Spotify, you can stop advertising this to me. I found it rather boring. Maybe it's a grower, whatever that means.

Japandroids - Celebration Rock
"The House That Heaven Built" is like this year's "Midnight City", so the album would also be this year's HUWD. But I like this one better.

DIIV - Oshin
Oh God, the reverb. Bits that have no singing are enjoyable.

Halfway through the year, yay. 

Songs I like that have a chance:

• Japandroids - The House That Heaven Built
• Grimes - Oblivion
• Beach House - Other People
• Sleigh Bells - Comeback Kid
• Catcall - Satellites 
• San Cisco - Rocket Ship

Songs I like that have no chance:

• Fiona Apple - Every Single Night
• Julia Holter - Marienbad
• Liars - The Exact Colour of Doubt
• Royal Headache - Surprise (not sure if eligible)

Songs that I may vote for because I used to like the artist and they are probably going to get in anyway:

• Regina Spektor - All The Rowboats
• Lisa Mitchell - Spiritus
• Missy Higgins - Unashamed Desire

Albums not yet released that may produce something voteworthy:

• The xx - Coexist
• Animal Collective - Centipede Hz
• Muse - The 2nd Law
• Sarah Blasko - ?
• Grizzly Bear - ?
• David Byrne + St. Vincent - Love This Giant

In the absence of someone to argue with (I miss you!), I'm going to post my thoughts here.

100. Mr Little Jeans - The Suburbs
This is interesting, though the sound doesn't really suit the lyrics.

99. The Beards - You Should Consider Having Sex With A Bearded Man
First time I've heard this. This is a novelty song, so I can't say much about it. I think it's rather weak.

98. Jay-Z & Kanye West - Niggas In Paris
Surprised that this isn't higher. That shit cray.

97. Foo Fighters - Arlandria
Hello, generic rock song. I have a feeling that I'll be saying that a lot today.

96. The Strokes - Machu Picchu
This Is It was great. This isn't terrible, but it's not that impressive either. Typical British stuff.

95. Grouplove - Naked Kids
Mercury Rev? Pixies? Is this one of those opportunistic indie bands that copies a bunch of sounds?

If Hype Machine is still going with their Zeitgeist thing, then it's not too late for me to waffle about my ten most-played artists of 2011.

Only the categories that I actually can have an opinion on. Might be updated as I get around to listening to them. Brought to you by my music teacher's campaign to convince me that there is good Australian music.

Edited on 13/10/11. Mr H completely disregards country, and we both laughed at the Adult Contemporary category's nominations, except for one, who was some guy from Hunters & Collectors. Also, I should check out something from the Fine Arts categories.

Edited on 1/12/11 to add winners and some comments, because I was too busy to do it on the night.

Underlined means I might go and look more into the band/artist. Italics means I already have it. Strikethrough means I missed it and I don't know it.

#100: Muse - Neutron Star Collision
Oh, Muse. You should do better than this. :(

#99: Dead Letter Circus - Big
Something than Gwen & co. like. It reminds me of the kind of J-Rock I used to listen to when I was into Japanese.
#98: Foals - Spanish Sahara
The Hipster Girls like this band. Pretty, but vocals are meh. Wouldn't mind checking out more of their stuff though.
#97: Parkway Drive - Sleepwalker
This sounds kind of awesome. Kind of.
#96: Jonsi - Go Do
So painfully hipster-sounding. But also more pretty than that Foals track. Oh, he's part of Sigur Ros. Unsurprising.
#95: Broken Bells - The High Road
Repetitive. Synthesizeritis.
#94: Xavier Rudd - Time To Smile
Boring. Oh, Australian.
#93: The National - Anyone's Ghost
Not bad, but I'm not really into this kind of sound.
#92: LCD Soundsystem - I Can Change
I don't really like electronic. Also, severe Ending Fatigue.
#91: The Bedroom Philosopher - Northcote (So Hungover)
"Gonna go down to JB Hi-Fi!" Okay, must look up lyrics, this sounds funny.
#90: Art Vs. Science - Finally See Our Way
Catchy, but I cannot forgive this band for Magic Fountain. Oh God, that'll probably be in the top ten or something. D:

#89: Interpol - Barricade
Not bad. Repetitive song, but I like the sound.
#88: Kanye West - Monster {Ft. JAY-Z, Rick Ross, Nicki Minaj & Bon Iver}
I will never like hip-hop. I can't get over the bad grammar.
#87: Birds Of Tokyo - The Saddest Thing I Know
Heard this song enough on radio already. Sounds a bit Maroon 5-ish too.
#86: Evil Eddie - Queensland
LOL. "Shake that gluteus maximus." Stay classy, Queenslanderps.

#85: Hot Chip - I Feel Better
This sounds like Vocaloid. I don't hate it, but I'm a sucker for strings of any variety, even synth.
#84: Washington - The Hardest Part
I loved this song for a while, but I got bored of it.
#83: Arcade Fire - Modern Man
Hell yeah, Arcade Fire. They'll probably have more songs up higher.

#82: The Black Keys - Tighten Up
Been thinking of checking out their stuff for a while now. Still haven't, but I'm interested.
#81: Klaxons - Echoes
Do all bands have crappy vocals nowadays? Might be the radio, but the song sounds horribly compressed.

#80: The Black Keys - Howlin' For You
Beginning reminded me of Uprising. Odd echo-y effect, like being in a venue with poor acoustics.
#79: Little Red - Slow Motion
PIANOOOO! Shitty vocals again. Sigh.

#78: Gorillaz - Stylo {Ft. Bobby Womack and Mos Def}
Memorable song, but I couldn't really get into Gorillaz.

#77: Big Boi - Shutterbugg {Ft. Cutty}
Once again, hip-hop.
#76: Kings Of Leon - Radioactive
Heard this too many times already.

#75: Hungry Kids Of Hungary - Coming Around
Last.fm kept reccommending this to me. Eh.

#74: Tame Impala - Lucidity
Don't know why, but this reminds me of The Beatles' more psychedelic stuff.

#73: Gypsy & The Cat - Time To Wander
Hmm. Undecided about this one. Might the radio that's making it sound bad.

#72: Two Door Cinema Club - I Can Talk
I like this! Vocalist sounds a bit like Ben Gibbard, but whatever.

#71: Gypsy & The Cat - Piper's Song
Snobs complain that all pop sounds the same, but a lot of indie does as well.
#70: Groove Armada - Paper Romance
MGMT-ish?

#69: Pendulum - Watercolour
Expecting this song. Heard it on the radio a few too many times, but it's still good. I just couldn't get into the album because it's so brickwalled.
#68: Andy Bull - Dog {Ft. Lisa Mitchell}
Hey, it's Lisa Mitchell! And pretty piano! Too bad it's damn impossible to pirate Aus music without torrents.

#67: Vampire Weekend - Holiday
Oh no, these guys. Theyre not bad, but I just find them annoyingly upbeat and calypso-indie.

#66: Cold War Kids - Audience
First song on here with a proper singer!

#65: Dead Letter Circus - One Step
Didn't catch all of this one because I went downstairs to greet my cousin, who had bought me a Lacoste iPhone case. :D Sounds a bit poppy.

#64: Gypsy & The Cat - Jona Vark
Again? I find them quite boring.
#63: Arcade Fire - Ready To Start
Wait, what? Already? We Used To Wait better be up high then.
#62: Angus And Julia Stone - Hold On
Didn't hear this because I was downstairs. I know I didn't miss anything exciting.

#61: Ou Est Le Swimming Pool - Jackson's Last Stand
Overplayed.
#60: Children Collide - My Eagle
Terribly catchy! I laughed at the lyrics when I first heard it.
#59: Washington - Rich Kids
Apparently this is about Brisbane. "Now I remembery why I left this town." The "Washington action figure" skit before it was kind of funny.
#58: Arcade Fire - The Suburbs
Already?! SMH, Australia!
#57: Example - Kickstarts
Nice voice.
#56: Sia - Bring Night
I liker her voice too, but not really into dance music.
#55: Vampire Weekend - Giving Up The Gun
A non-hyper VW track! Actually sounds not bad.
#54: Miami Horror - Holidays {Ft. Alan Palomo}

#53: Bliss N Eso - Reflections
I've always sort of liked these guys, even though it's rap. I think I like the rap of the non-electronic variety.
#52:The John Steel Singers - Overpass
#51: Yeasayer - Ambling Alp
#50: Hot Chip - One Life Stand
Mehh.
#49: The Jezabels - Easy To Love
Piano ballad! I'm intrigued.
#48: Pendulum - Witchcraft

#47: Birds Of Tokyo - Wild At Heart
I like this song less less than the other one that made it on the countdown.
#46: Bag Raiders - Way Back Home
#45: Boy & Bear - Rabbit Song
#44: Crystal Castles - Baptism

#43: Yolanda Be Cool/DCUP - We No Speak Americano
I don't like this, but I expected it to be higher.
#42: Gorillaz - On Melancholy Hill
As expected.
#41: Bliss N Eso - Down By The River
See #53.
#40: Gyroscope - Baby, I'm Getting Better
Overplayed.
#39: John Butler Trio - Revolution
I think we're entering "songs I've heard on the radio every day" territory.
#38: The Naked And Famous - Young Blood
Wait, this isn't Passion Pit? Wow. Sounds exactly the same.

#37: Gorillaz - Doncamatic {Ft. Daley}
18 plays in my library, which means I liked it but got bored quickly. But I would have voted for it.

#36: Chiddy Bang - Opposite Of Adults
It annoys me when I immediately pick up what a rap song is sampling.

So tired of that Golden Ticket ad.
#35: Mark Ronson & The Business Intl. - The Bike Song {Ft. Kyle Falconer & Spank Rock}
This isn't bad. "Gonna ride my bike until I get home." Well, that would be the smart thing to do, right?
#29: Illy - It Can Wait {Ft. Owl Eyes}
Wasn't paying attention, so I'll assume it was boring, as well as the following:
#30: Yeasayer - O.N.E

#31: The National - Bloodbuzz Ohio
#32: Foster The People - Pumped Up Kicks

#33: Tame Impala - Solitude Is Bliss
Once again, I will say: Beatles with more drugs.
#34: The Naked And Famous - Punching In A Dream
I didn't like Passion Pit and I sure won't like a band that sounds like them.

#28: Darwin Deez - Radar Detector
Cute indie pop.

#27: Florence & The Machine/Dizzee Rascal - You've Got The Dirtee Love {Live}
This is bizzarre.

#26: Crystal Castles - Not In Love {Ft. Robert Smith}
***OK, at this point I fell asleep intermittently, so I'll only comment on what I know***

#24: Sparkadia - Talking Like I'm Falling Down Stairs
This was not bad at all. Though the fact that this their only song here means they probably just got lucky.
#23: Bliss N Eso - Addicted
See previous Bliss N Eso comments.
#21: Two Door Cinema Club - Undercover Martyn
#20: Washington - Sunday Best
I fell asleep during this...
#19: Flight Facilities - Crave You {Ft. Giselle}
...and as a result missed this, which was a shame, because I really like this song.
#15: Duck Sauce - Barbara Streisand
Ugh, this song is terribly annoying. Glad I was asleep, and it didn't get in the top ten.
#14: Kanye West - Runaway {Ft. Pusha T}
I woke up in the middle of this, right before the vocoder part. Interesting.
#13: Sia - Clap Your Hands
Haha, my father asked what this is everytime it comes on. Everything about it is quite forgettable.
#12: Drapht - Rapunzel
Annoying rap.
#11: Pendulum - ABC News Theme {Remix}
EPIC. Noo, it should be higher! If Magic Fountain wins I'll be pissed.
#10: Mark Ronson & The Business Intl. - Somebody To Love Me
Reminds me of Cee Lo for some reason. Kind of annoying, since I've heard it so often lately.
#9: Art Vs. Science - Magic Fountain
Announcer to band: "Are you aware that it is the stupidest song ever? It's crazy bullshit...I don't think it's a song anymore. It's like, a force." LMAO.

#8: The Wombats - Tokyo (Vampires & Wolves)
So yeah, I was expecting this to be up pretty high. But it is ridiculously overplayed, and doesn't have enough staying power to not annoy me. Twitter: "Nova called, Triple J, they want their music back."
#7: Cee Lo Green - Fuck You!
I shouted when this came on. This was my pick for #1. The rest of Twitter seems to have the same reaction.

#6: Adrian Lux - Teenage Crime
OK, this song isn't terrible. But I don't like it either. :/

#5: Boy & Bear - Fall At Your Feet
Eh? A cover is #5? It's nice, I guess. Also reminds me of the time Mumford & Sons covered a Vampire Weekend song, and slowed it down a ridiculous amount.

#4: Birds Of Tokyo - Plans
RT @whatamindblast: They should call this song "Blands".

#3: Ou Est Le Swimming Pool - Dance The Way I Feel
*shrug* Overplayed, I guess.

#2: Little Red - Rock It
I don't hate this band. Their general sounds seems pleasant enough.

#1: Angus & Julia Stone - Big Jet Plane
:| Yeah, I typed this out when they started playing Rock It. Predictable. I'd probably like this if it weren't for the stoner voice. Why are they so...derpy? The live version actually sounds better than the recorded version.
