Quite a few of the acts were outdated, superceded or downright embarrassing.
Roger Waters: I mean wtf, his best stuff is 30 years old. He should go live on some long boat in Cheshire somewhere.
Police: Tighter than ever, great stuff. High light...everything, low point, Kanye (I got nuttin' witout my ho's) West.
DMB: Christ, they are getting better with age.
Alicia Keys: Hawt AND talented. Set w/Urban was perfection.
IMHO, of course.
