What's your workout music playlist like?

Simple I think, when you workout, how does your playlist tend to go? Is it just straight metal/rap/(insert genre here)? Is it just random? Or do you have a warm up genre/song, a work out genre/playlist, and a cool down song/genre/playlist?

Mine tends to follow something like this:

Warm Up: Noisia – Machine gun (16 bit remix)

Workout: normally start out with metal or something with a fairly fast angry or powerful beat. Something like Slipknot – People = Shit, Wagner – Ride of the Valkyries, T. Rex – 20th Century Boy, etc. Then it can go to whatever genre.

Cool down: something slow like Staind – Outside or Damien Rice – 9 crimes
