Everything! But not really. haha (while I think of a conversation recently had)
But primarily Indie, punk, rock, hip-hop, metal, some rap, a dash of country, a pinch of classical, throw in a bit of reggae, and even some electronic stuff. It's all good for the most part, notably though, I dig 311, Incubus, Muse, 30 Seconds to Mars, Rise Against, Social D, Smashing Pumpkins, Missy Elliot and The Black Eyed Peas to name a few.
