I have a few:
1. The Doors... most overrated band ever.
2. Mama's and the Papas...make me wretch.
3. Styx - though eventually I grew to ALMOST like them
4. Van Hagar ... though Sammy solo is "OK".
5. George Thorogood
6. The Ramones.... WTF?
And when I was younger, I really hated Jimi Hendrix.... now I sort of enjoy him.

I liked some of the punk bands but could never understand how those guys ever got a recording contract.. 
There's a couple studio recordings of them that I do like, but overall I thought they were a big snooze-fest.
