I don't know why I didn't think of this before, and I have done it in other games, but if you want to eliminate the music completely, you can either "mute" the audio file itself, if you are familiar with audio editors, or delete the file, and then replace it in name only, with a 'zero-length' file. You right-click in the Music folder, choose "Create new text file" on that context menu, name it the new file the same as the file just deleted and press <Enter>. Now select that new file and then change its name to not have the ".txt. on the end, if necessary, to just have the FileName.ogg
