A few other links:

http://www.acidplanet.com/ - a place where people share their Acid generated files. Neato. Acid is simple, loop based audio. Not to imply that it's "simple" or anything. There is a free trial (pro) AND a free (limited featureset) version available. Finally tried it today - pretty spiffy stuff.
Some royalty free tracks at the Open Music Registry. Not that much selection, but it's a start.
