Any final fantasy 7 rebirth soundtrack gurus around? I've been trying to track down a music track for a long time. No, the official soundtrack does not have it, despite it having some 180+ tracks.

So anybody that's played rebirth knows that all the major areas have an escalation of music as you progress through the area and complete quests. Every area has basically three versions of its area's music track that plays, and those music tracks change or update and upgrade as you progress through the side quests. With all this being said, I have been trying to track down the very first iteration of the music track for Corel Desert that plays. The very first version that you'll hear for a while in the area before you've done any other side quests and upgraded music. So not the second smaller upgraded version, and not the third final version. The first one. If you go to YouTube right now or you find any soundtrack for rebirth, the only Corel Desert track you'll find is the third version, the one that has all the instruments all the updates, everything. I'm trying to find that first iteration. I've searched other soundtracks, I've found playlists that say they have other music tracks that aren't on the soundtrack, I've tried SoundCloud and reddit in all types of places but I can't seem to find this very specific one. I've even looked into trying to rip all of the music, every single music track, from the PC version, but I can't find a guide either. And even if I did, I'm not even sure what format it would be ripped as, and then I would have to figure out how to convert it to another file format, like MP3.

I realize this is a hyper specific track to find, but I've been trying for weeks now and I just can't. Can anyone help?
