Magnatune also allows really-cheap licensing of any samples used to make new music, such as (for example) $90 to print 500 CDs.

Victor Stone has made his massive Magnatune sample library available. Every sample is already perfectly looped, and has BPM and key information, as well as metadata in the right format so that it imports automatically into sampling software.

those samples (like everything) are CC by-nc-sa licensed, or can be commercial-use licensed.
