The only band I can think of where this has happened is The Cure. Someone I know loves them so they made me listen to 2 songs, and I thought they were rubbish. Well not rubbish, but just not my taste at all. I didn't bother listening to them again for several months, but then by chance I heard a different song from them and it sounded like a completely different band. Now, I can't find any songs by them I don't like apart from those 2 originals that I hated. Kinda strange.
