An open source project called Sockso already implements much of the backend music handling(ie maintaining a database of music, automatically encoding, and playback). It was designed for streaming music to other users. As such we decided to branch this project to add our features such as dynamic playlist editing in response to voting, and our substantially different interface. The original project can be found at http://sockso.pu-gh.com/
