flash.display.Loader has a nice function, 'loadBytes', which
takes a ByteArray as a parameter. Is there no way to load an mp3
from a ByteArray as well? The only method I could come up with
involved embedding the mp3s, which I hope to avoid, since I do not
feel like wrapping every mp3 that comes my way (it's a lot of
pointless work, and then the data can only be used in flash 9).
