Well, I couldn't exactly choose the choice that I wanted, but I guess I'll go with rock on this.
For me though, I'm not a very bit genre type person, with large exception of experimental music because it tends to blend in a large mix of genres. Bands really shouldn't restrict themselves to composing music only of one genre, it needs to be spread out a lot.
Anyways, yeah...that's my whole deal with that. But my lovely set of music genres I tend to listen to most include Experimental Rock, Progressive Rock, Fusion Jazz, Post-Rock, and I guess alternative rock...however I've never really understood that term all that well.
