Decoding Minecraft MUS files
In search of decoding Minecraft .mus files, I found a great, portable and tiny tool, called MusDecode.
MusDecode developed by Nico Bergemann and it’s a java command line tool.
To use it you can simply provide for argument the .mus file or folder with .mus files want to decode. After a very little time, you got OGG files at the same with given MUS folder.
