I think it would be prudent to have them separate, they're different enough to be considered different formats, for one thing MP3 uses UTF-8 exclusively, while MP1 and 2 use UTF-16 for the strings. --Antidote (talk) 16:46, 25 January 2015 (CST)
Probably a good plan then, I don't know the MP3 format at all. --Parax0 (talk) 16:46, 25 January 2015 (CST)
