Using .mus files. (Windows Vista)

I need help changing files of the .mus format into .ogg or.mp3 files; I use Widows Vista.

.MUS files may be Finale files, in which case you will need an appropriate version of Finale to open them.

.MUS files may be Minecraft music files. Apparently there is a decoder for these called “musdecoder.jar”

There are also several other (different) formats that a .MUS file could be (search for “.MUS file” on Google).

Audacity does not support either of these file types so you will need to convert them to a supported format before you can use them in Audacity.
