I don't know if you can decide on a Best Album of the Decade until it's over, not just because of what may come out in the next 3 years (we do have at least one more U2 and Radiohead record coming out), but also in terms of how well all these respective albums age. I love Funeral too, but it just came out a couple years ago. Will it be as strong in 2010?
Here's a shortlist of contenders that I won't bother to rank:
PJ Harvey, Stories from the City, Stories from the Sea
The Arcade Fire, Funeral
U2, How to Dismantle an Atomic Bomb
Radiohead, Amnesiac
Super Furry Animals, Rings Around the World
Bob Dylan, Love and Theft
Sleater-Kinney, One Beat
