I make my own MP3s.

The method is a little lengthy, and hard to read in this BBS format, so I made a page here:
http://www.nortonmusic.com/backing_tracks.html

I do this for my very successful duo, The Sophisticats, http://www.s-cats.com. You can hear a demo medley culled from our live performances on The Sophisticats site.

I plan on eventually selling mp3 backing tracks, right now I'm working on getting the licensing to do so.

I hope this helps.
