A song that I forgot to include in the main files:
A Easy Enemy replace a Sigma 1 track from Chapter 3.

Black MM OST over Sigma 1 Main Menu OST

Issue:
After you beat the Chopper Boss in the Military Base the Black Main Menu OST will play,
no way to modifier the main menu track without change this song because the game reads the same file for both areas.

Replace City of Fiends with Tairon at Night, ignore this unless you're like me and don't like City of Fiends song.
