Sorry to toot my own horn here, but if you want something that you can be sure nobody else will be using, you can try
my website. I do custom-composed floor routine music, written just for your daughter.
Another of my favorite music resources is
OverClocked Remix. I highly reccomend anything by zircon (just do a search for "zircon" in the "remixer" search on the left side of the screen). If you can give me a more specific idea of what you're looking for, I can reccomend some other artists as well as specific tracks.
And, as I've said before, just about anything by Bond will make great routine music. My favorites are Explosive, Fuego, Duel, and Scorchio (though be warned -- these seem to be getting more and more popular; they haven't yet gotten to the point where I'd call them cliche and overused, but Explosive and Scorchio are definitely approaching that point, and Fuego isn't far behind).
