Add sound play cabability to dynamic website - repost

This project is to add sound-play cabability to dynamic website which is based on Django. Right now I'm listing songs in a dynamically updated list (it's html with javascript), and I want to add ability to play the sounds. They are midi files, so fluidsynth will be used on the server side to make them into mp3's before they will be played. This is one part of a larger project. Planning for the future, I'm looking for an individual who can continue to make contributions over time, which will be created as separate projects in the future. If you know about MIDI, that's a big plus.
