Javascript mp3 decoder

Well, it allows you play mp3 files in browser without Flash.

Interesting discussions with the developers on HN: http://news.ycombinator.com/item?id=2665821

Even if this is honestly what it claims to be, it's still fucking useless as anything but a tech demo -- every modern browser has mp3 playback built in. And as far as Javascript tech demos go, I can think of far more interesting and useful ones than mp3 decoders, even within the field of audio playback: how about a Javascript .mod player?
