Created to sate Client-Side JavaScript Waveform Visualizer because it piqued my curiosity.
Allow uploading of audio clips, thumbnailing them with a waveform, then using HTML5 audio to play them back in a browser with a scrobblable/seekable waveform.
It looks like your site is Django, but similar concepts can be applied, and you're uploading audio files. Thumbnail their waveforms, just like Soundcloud and other self-respecting audio sites and similar HTML5 audio demos, turning it into a scrobbler.
