Wouldn't it be more wise to first work on things that are already implemented by the W3C?
While there are already third party plugins/players for MOD/XM out there, I can't find any mention of it within the official HTML5 specs.
EDIT: Just ran into some unknown behaviour.
When I re-imported a .WAV file to a project that still had previous conversions (albeit only .M4A, not OGG), it would not only rename the files from Dark Forest.(fileformat) to dark forest2.(fileformat) but also list dark forest2.wav under audio.
Now naturally, the .wav is neither exported nor is it called from within .js. Still an interesting phenomenon. Has this always been that way? I assume this is in order to compare the original .wav with the conversions?
