does anyone know some names of some freestyle music?

anything you want to use. It used to be done with a lot of classical music or movie themes (star wars, etc.) Now it has seemed to gravitate towards a younger more hip movement. Its whatever you like. Ideally a good beat, and tempo that changes movements works well. With todays music many times you have to mix several songs together.
