Late to the thread I know, and nothing new or different from above choices but:
Can't stand Slayer.
To this day can't get into Judas Priest, except for a couple of songs.
Bod Dylan and Bruce Springsteen should be shot in the knee, you know, just to teach them a lesson.
What is the big deal with The Rolling Stones? Granted, maybe becasue they've been around FOREVER we only here their "hits" now and I may be deprived of a REALLY hidden gem here and there, but overall, can't stand their music.
Why do people Worship U2? it's a pile of pop crap, except, again, for a couple of songs.
