Very interesting feature. I'll try saving a few audio files on that folder and see the results.
BTW, a good feature is to add support to chiptune soundtrack files, such as:
*.nsf -> NES
*.spc -> SNES
*.gbs -> Game Boy
*.vgm -> Genesis
This way, anyone can use game music directly from its original format. Besides, these files are really small, so a 5 minute game music can have only 100kb.
