This is an interesting idea. I'll run Google, Yahoo!, Acoon, and AltaVista searches for your band and song title(s) and see what free downloads I can get; knowing that, I'll assess the openings and clog them up with fake files in order to direct them to your preferred methods of distribution.
You know I'll do a good job because my brother is in the music business and he could benefit from what I learn doing this for you.
