If you want to give a little synopsis of why , go for it.. Mine are
1: Guns n Roses. Music wasn't bad until axle started singing. He sounds like somebody is strangling a cat.
2: Metallica. Never liked them and then they went and played with an orchestra. Do you headbang to a orchestra?
3: The Beatles ... They're just horrible.
4: Aerosmith . See above.
5: The Eurythmics, or anything Annie Lenox. Changing the radio station every time I hear her voice.
Honorable mention : KISS. They were horrible but at least they didn't pretend to be in it for anything other than money.
