Ah! I think @Jack Rackham's trick requires the new music case to be added to PROGRAM\SOUNDS\sound.c as well.If you mean 'music_standard.c' then yes
Code://============ JACKTORTUGATAVERN ======= tmpref.music_jack_tavern.f1.name = "MUSIC\JackTavern.ogg";
Also, note that if the filename is "JackTavern", but you name its alias "jack_tavern" in code, you'll be needing that underscore.
