I hated the Talking Heads in HS, when they were big (graduated in '84). Learned to love them in college, and still enjoy listening to them today.
Never was a fan of Led Zeppelin, i could maybe listen to Stairway to Heaven, but that was about it. Then, however many years back, within the last 10, I think, they started using some of their songs for Cadillac ads, and I was like, wow, i actually like them! Although they still fall under the category of band who I can only listen to a few songs at a time.
I used to love Billy Joel, James Taylor, that type of stuff. Then went through a period where I couldnt' stand them. I'm just now beginning to appreciate them again.
