Just a thought. Maybe you can leave it as mp3, since that's so common, but in your Legend, call it:

mp3 = online digital audio release (MP3, AAC, etc.)

Since that's what you're really trying to distinguish it as, right? An online digital release, as opposed to a physical medium, like compact disc, vinyl, etc.
