For my "formal" workout I'm listening to the music Chalene plays on the Turbo Jam dvds. I LOVE those songs, they fire me up and get me ready to go!
But when I'm doing my "informal" workout, aka dancing with my two year old daughter, we listen to other stuff that my daughter chooses. This week our favorite songs to dance to are "Boom Boom Boom Boom" by the Venga Boys and "Giddy Up" by Laura Bell Bundy. We're also liking DragonForce, especially "Operation Ground and Pound" because it's good for making you want to jump around like a crazy person and headbang.
