a lot of progressive metal, lots to listen to and I don't have to switch songs as much during runs since they're well over 10 minutes generally, lol

favs are dream theater (of course ;P), tool, symphony x, opeth

other bands I like are lamb of god, children of bodom, amon amarth, arch enemy, battlecross, cc, in flames, kalmah, testament, etc.

then of course there's the weird stuff I occasionally indulge in, like mr. bungle, puscifer

oh and I like the fox
