Have heard multiple people and sources claim that the stage music is Redbook Audio, and the Saturn is doing some kind of funky processing to make it change according to the A-Life elements. This is false. Complete untrue. It's a MIDI format, or at least some other format than plain Redbook audio. I can know this confidently because so many Saturn games do just use unaltered Redbook audio for their music, to the point that you can just put it in your computer and rip the soundtrack... but this doesn't work for NiGHTS. A lot of stuff does get ripped, but the stage themes are nowhere to be found.
