Interesting. That being said, if I had no knowledge of any other music in the 2000's, I would say "wow, what a crappy decade of music". I realize they had to gravitate towards singles and such, but I am not surprised by some of the mediocre selections. It looks like a list of what Pitchfork would pick. Of COURSE the Yeah Yeah Yeahs, Radiohead, Animal Collective and Arcade Fire would be included in the top 10. Now if Magnet (the magazine) put out a list, I think it would probably be more suited towards my tastes.
So that being said, if I had to pick my top 10 songs of the decade, it would gravitate towards the stuff that I never, ever get sick of:
Queens of the Stone Age -- In the Fade
Elliott Smith -- Everything Reminds Me of Her
Death Cab For Cutie -- Transatlanticism
Yo La Tengo -- Our Way To Fall
Belle & Sebastian -- Jonathan David
Interpol -- Leif Erikson
Fischerspooner -- Emerge
Sleater-Kinney -- One Beat
Eagles of Death Metal -- Speaking in Tongues
PJ Harvey -- A Place Called Home
