The Band of the 2000s

Okay, so a while ago I put up a post wondering who the band/artist of the 2000s was. To recap, a lot of people think that Elvis was the artist of the 1950s. The Beatles was the band of the 1960s. Led Zeppelin was the band of the 1970s. U2 was the band of the 1980s and Nirvana was the band of the 1990s. Now again, who would you say was the band of the 2000s.
