For me would be Bruce Springsteen's The Seeger Sessions - released April this year. I'm not a wild fan of the boss, but this album is really excellent ! If you want one track try "She's the One". Oh OK two tracks, "Mrs McGrath"
My best current album would have to be Girls Aloud and their album "Chemistry". I just LOVE Girls Aloud: I own ALL their albums and always listen to them. "Sound Of The Underground" also rocks.
