When I workout I usually pop my Slipknot CD. There is just something about a song that continously sings about Fuc**** the world that just makes me want to get ready and bash someones face into the mat. But if I am not listening to Slipknot I am listening to a bit of techno. John Digweed, Crystal Method, Ian Van Dahl, or Chemcal Brothers. It is all good stuff with a a** kickin beat.
