Fair bit of rock, mainly alt/rock I guess (for rock that is), metal - well many types, into a little "nu-metal" such as Mudvayne and Deftones. More into the European metal, melodic death, heavy etc. Bands such as Soilwork, Children of Bodom and Opeth. Opeth are particularly good, their music is excellent all round.
And who can forget the old favourites, Tool...not to mention the Maynard spin-off, A Perfect Circle. Crap, forgot; Pantera's good.
Oh, almost forgot, been listening to a lot of Nirvana lately.
Edit: after all that! No, I don't play an instrument. Played keyboard for a year or two but showed no dedication what-so-ever.
