Your own favourite type of music and another kind of music that you don't like

[Tiggi]

I've moved this to a more appropriate location.

I'll have a go:

Like - Alternative Rock. For me, music that has a bit of an edge goes down very well. Since edgey music is best done by artists from the Alternative genre (IMHO), that's where the best stuff is.

Dislike - Bolivian Nose Flute music. Sounds far too unhygienic...
