There is of course floorexpress, the most famous company for music. I too have a fledgling company with quite a few songs. No demo CDs out yet but if you're interested I can give you a pre-publication copy with about 15 songs.
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).
Does anyone have Ivana hongs music? Floor express and Energym do not. I have also checked with wolfmusic. For months I have checked many sites and sent out many emails etc to find this for one of my students. Can anyone help?
