+If you don't like or have trouble getting the original X-Com music to work, you can use your own by putting it in the SOUND subfolder of the Data folder with the same filename as the original (GMGEO1, GMGEO2, GMSTORY, etc). The formats supported are MIDI, MP3, OGG and MOD. You might need to delete the original music (including GM.CAT) for it to work.
