I think the music for the good ending (saturn version) should've used the good ending from the actual game instead of the title screen music.
There are two reasons actually: the first is that I needed a track with the right duration to fit for my cutscene, and the second is that a friend remixed that short track for the scene.
You still have the custom music option to put your own version if you want. Just follow the guide into the Custom folder to do it.
