Depends on the type of mood I'm in...

Always to get me started something like Van Morrison(that man's voice makes me warm inside) or The Doors

If I want it harder, then some hard techno or something like Disturbd or System of a Down

If I want it slow and long, then R&B, Wyclef Jean, R.Kelly, Alicia Keys, etc.
