Thanks for the support and you're welcome. The one thing I noticed that was, indeed, captured very well are the cinematic/cutscene tracks. I think you uncovered even a couple unused ones as well. There were two tracks towards the end of the game that I thought were identical. The one right after you defeat the last form of the Traitor and the one after Johnney and the President make it back to the surface. It's essentially the same song, but the one with the added few seconds on the beginning was for the boss ending. Gah!
Well, if you do take a look at it again, hopefully it isn't a case where three tracks are playing at once and they are all divided up into drum kick, a few effects and the main song (fingers crossed it isn't like that!)
Got some real life issues going on right now that I have to take care of first, but I'm hopeful I can do some more direct naming of the different files to make the process a little easier.
I'm also re-playing the game on hard and ultimate. I doubt there's any differences in the storyline or the level layout, but I'm thinking of doing some double-checking on a few tracks. The only reason I'm re-looking is that I might be able to ID a few tracks that weren't IDed before. Figured I'd try to play up to after the first boss again as I know for sure I was quite meticulous after that point for sure.
If anyone else feels like playing through the game, this initial research sweep should make things a bit easier than IDing from scratch as the games music tends to change subtly from time to time. If playing by emulator and you're less interested in the gameplay, I recommend activating the 9999HP cheat. Cheats like Max Stats seem to drop all your attacks to zero and, I think, level 999 cheat disallows you from exiting battle even after defeating the enemy. I think the all items cheat won't negatively impact gameplay. I wish this just speeds up the process of working your way through the game, but it will probably only moderately speed up the process and almost eliminates any chances of dying (you can still accidentally fall into a pit and die anyway, but there's very few areas with that being a huge risk - mostly Bross's lab in the second level actually)
