Nothing. Absolutely nothing, except when I am in the car. I keep my computer on mute at work and unlike the guys around me, I don't subject others to my tunes. (The guy behind me plays oldies which aren't too bad, but the stuff on the other end of the bookshelf is just atrocious!) At home, my computer is so fouled up I run it on safe mode so no sound. In the car I have mostly been listening to Megaherz with a bit of Rammstein thrown in. Since it is getting warmer out I might throw the Damian Marley CD back in the player.
