I have to agree with a previous poster, I do not hate any bands but there are always a few that I dislike....the one that jumps to mind for me is ...
Iron Maiden....definitely overrated....
I'm not surprised that many do not like the major bands from the 70s(such as Led Zep and Aerosmith, 2 bands that I love) as that is a generational thing...which is probably why I can't stand most of the 'modern' rock/metal bands .....
