jukey
jukey pygame-based jukebox software. It is developed on GNU/Linux -- it may work on other systems where pygame works, but I have no confirmation of that as of now (email me if you've got it working, especially if you have changes).
google-code entry.
Features
- visual interface: click album covers, icons
- behaviorally-animated interface (albums fly places, etc)
- supports ogg, mp3 (anything pygame supports)
