When I'm cleaning Mike's pencils I like to listen to my Music (or the Adam Carolla Show).
My new favorite indulgence is a website that has hours upon hours of Nine Inch Nails music - a collection of remixes done by tons of different people. You can just hit play on the playlist and it goes and goes and it seems familiar but not at the same time. If your a fan or not - check it out. There is something for everyone.
Oh and Soulfire is cool stuff too :)
