A MGU song file uses the melody track while a SGU song file has a blank melody track.

Let's say you have two "Farmer In The Dell" song files. If you want to play the song file that includes the melody then you would select farmer_in_the_dell.mgu. If you want to play the song file without the melody then select farmer_in_the_dell.sgu.
