Hmm...

Here's what you can do:

1) Get Winamp2 and an add-on to read those files.
2) Use the disc writer to create a WAV of the song.
3) Make that song an instrument in a tracking program, preferrably MadTracker or FastTracker.
4) Use it at the beginning and make enough patterns to make it full.
5) Listen to your new Mod, see if it is okay.

If you follow these five steps, you will have done it!
