I really wish there was a version of this where things are just... already put together? I don't understand all this stuff about putting code in files and loading files into WADs. Also, I can't find any ogg files in the zip where the Music Pack document says they should be. ALSO also, I can't find a document called "dynmusic.cfg".
What you're asking for completely goes against how the mod is designed. From the start, the intent was for individual players to customize music on their end, not to be subject to whatever the server decides on. Example usage and a reference for the commands is included in the mod's zip, so you might wanna see what's going on there if you're confused.
