While it's difficult to put a somewhat non-linear game soundtrack like QFI "in order", here's my attempt:
(Note that while the tracks are in order of the game events, some tracks are grouped due to non-linear geographic areas/screen progressions, and others are grouped according to class - Brigand, then Sorcerer, then Rogue)
(It also seems like I was able to get the "Surfing with the Centai" track to trigger somehow, but I cannot remember how to do it again to determine where it should be placed...)
