Hi crewgirl
I don't know if this helps, but I run a small arranger keyboard forum, (see sig.) where we upload original compositions and covers that have been produced solely on our keyboards. One of the members has started a site providing music, (any genre), for dance classes and is offering payment for any tune that gets downloaded, whether it's original or a cover. (He has the necessary industry permissions to offer this service).
I tend to agree with Fisicx as far as providing music for websites is concerned. I find it a big turn-off. However, I'm sure many people do enjoy hearing music on visiting a site, so I wish your friend luck in this respect.
