This is probably my first "real" C64 composition, and also my longest at 3 minutes and 8 seconds.
This track was done in DefleMask. I have no idea how to GoatTracker at the moment. If I knew how to GoatTracker I would have done this track in that instead.
BTW I actually had to bug the DefleMask devs to get this to export properly. I have no idea if this will play on an actual C64, but you're welcome to try.
