open source music streaming api

I would like to stream music (not random, specific...e.g if i want megadeth - peace sells i should be able to stream it) to the clients from the server. grooveshark came to my mind first, but it doesn't have a开发者_如何学Pythonn open api that i can use. do you know any facilities like grooveshark that has an open api?

I found links to a GrooveShark API on their site. Interesting API calls that seem to do what you want include...
