Qualification dates run from October 1 of 2004 to September 30 2005, therefore I don't think Bomb qualifies for Album of the Year this year.
The Grammys are always wacko anyway. No one knows what the hell the voters are thinking half the time. Back in 2001, U2 won Best Song, Best Rock Performance Band or Duo, and Record of the Year just for Beautiful Day.
The following year ATYCLB won Best Rock Album, Elevation won Best Rock Performance Band or Duo, Stuck in a Moment won Best Pop Performance Band or Duo, Walk On won Record of the Year BUT O Brother Where Art Thou won Album of the Year.
Soooo, ATYCLB behind won 7 Grammys on the strength of four different songs. But O Brother won Album of the year.
Steely Dan won Album of the year the previous year.
Don't you remember when Jethro Tull won Best Hard Rock/Metal Performance Vocal or Instrumental beating Metallica at the time.
There are way more examples of awards after which people were like HUH?
