Wav. files, MP3's and any related media will not work with JJ2 and the conversion to a suitable module type (.mod, .xm, .s3m, .it) is too hard to be worth it. That's because MP3's and Module files store the music in two different ways:

- wav's and MP3's store the sound itself, they're like recordings. Because of that, a lot of details have to be stored, and that's what makes the file so large.
- modules and MIDI's are like sheet music. They're not recordings, rather they tell the computer to play "this tone" on "this instrument" on "this spot". MIDI's and modules differ in that modules have the instruments called "samples" built into the file. The combination of sheet music and built in instruments bring the file size down considerably.

Module into MP3 is a no-brainer, but MP3 into module is... practically undoable. What ModPlug Tracker basically does is convert the .WAV into one gigantic sample: one JJ2 can't handle.

Fortunately, some artists have created their own interpretations of the music found in games, some have even managed to recreate the exact music from scratch.
