the soundloud shopsystem looks fine to me but 2 things are bugging me:
1.mp3 limited to 10 mb in size (effectively 6 min 192 kbps)-I want to sell 320 kbps so I need up to 25 MB per track
2.no real verification - anyone can open an account there and "sell" Madonna songs ? bit of a loophole.
But yeah I'm givin this a shot, see how it goes...beside the size restriction it should really work for indie EDM producers like this
