Music you HATE the most but once you LOVED it

U2 takes the cake for me on this one. I don't *hate* them, but Bono makes me cringe nowadays.

(cringe) Alan Parsons Project.

I don't agree to your thread. As a music lover I might NOT LIKE certain music. But HATE....that is too strong a word for music, and it is not what I feel. I used to listen to a lot of pop music as a teenager that I don't like to listen to any more - especially the ones with "electronicky" music, as they feel "noisy".
But hey, I do enjoy dancing to some new music with my 4 year old on the new songs from Beyonce, Britney, Lady Ga-Ga, Timberland, etc. on his mom's iPod connected to some computer speakers. And I don't like to these "numbers" on my main system.

Disco!!

First thing that comes to mind is the Cat Stevens album "Tea for the Tillerman". At the time when it came out, I thought that it was so great; now I think that it's incredibly trite. I think he was just pandering to a certain audience at the time, and he was just a polished poseur. What a jackass he turned out to be.

Well, hate is a strong word but here's a few that don't get much play time here:

3 Dog Night
Fleetwood (Buckingham/Nicks) Mac
Bad Company
David Bowie
Grand Funk Railroad

Most of the music from the 60's, 70's and 80's, it's all old news now!
