Music you HATE the most but once you LOVED it

ac/dc for me. when mr scott checked out (rip), so did i.

Okay, I gotta defend Bob.

Ain't no way you can hate any album that has "One Too Many Mornings" on it.

Period.

Gentle Giant

Opa Trio

I think you all really hate these groups like you've come to hate being married.

Okay, as already said, "hate" would be a little strong for any of this, but...

Doobie Brothers -- loved tunes like "One Step Closer" when I was in high school...
ELP -- yes and no. Just cued up Tarkus on vinyl for the first time in many moons and it sounded great. Still like a lot of "Trilogy." Brain Salad Surgery's become unlistenable for me, though.
Al Jarreau...
