Which final fantasy? PC, PSX? I have 7 and 8 for PC sitting here, I couldn't get either them or Homeworld to play in a stereo, either, so why are you thinking there are music tracks? Are you talking about bonus sound track discs or the game discs?
Homeworld has a HW_Music.wxd file that's 100mb on it, where I assume the music is stored, so unless you have a special edition or something, I don't know what you're talking about, because it's not redbook audio like say, Mechwarrior 2 had.
