I'm going to say all music except rock produced between 1970 to 2000 and even then there are some exceptions. Country sucks! Rap sucks! Folk music is nothing but burnt out hippies. Techno and rave music, what the hell is that? I think you need to be on drugs to understand that. If I am forced to specifically mention one band there is a local band that sings folk songs at a local theatre near my house. Thanks to their vocalist, In my neighbour's words "I think I know understand what it sounds like when a cat is being raped."
