This was inspired by Project Noise; a larger-scale TWEWY project spanning pretty much the entire game. Special thanks to Project Noise team member Oluvids, whose tutorial on modding KH3 music taught me everything I know. Be sure to check it out.

For compatibility with Project Noise, ensure that these mods loads after Project Noise.
For my mod setup, I added a Z to the start of the Project Noise .pak file name and at least 2 Zs to the file names of my own mods.
(ie: zpakchunk99-Project Noise Music.pak, zzKeyblade Graveyard Finale BGM.pak )

For this project, I deliberately picked tracks that were different from what Project Noise chose, both out of respect for that mod and to set it apart. There are a few exceptions (ie: SHIBUYA for the field theme, World Is Yours for the Nort Court) where I simply couldn't think of anything better, but even then, I edited the audio myself instead of using any files from Project Noise. Content theft is out of the question and besides, making mods is a learning experience for me. There wouldn't be any satisfaction in nabbing other people's work.

Been working on this one for a couple of months. Originally it just covered the final boss + Limit Cut Episode, but I had ideas for Roxas and Terranort, thus the project snowballed and ended up covering the entire Keyblade Graveyard world. Editing the cutscene music to line up with the original BGM was another challenge, but it made for a more cinematic experience and I'm satisfied with how it turned out. This is by far the most ambitious project I've done, so I might slow down/ease up on modding for a lil' while.

Note that this mod is untested with ReMind (Limit Cut Episode notwithstanding).

Vanitas: Transformation -NEO MIX-
Vanitas' Death: Beyond Oblivion
From Chains to Bonds: hopeless + Breaking Free + Sentimental (My personal favourite. I'm particularly proud of how this turned out.)
Saix and Xion: We're Losing You (I felt the lyrics were appropriate for fighting Saix and Xion. I'm particularly satisfied with how it transitions into the cutscene.)
Cutscene: NEW GAME + Menace + Anxiety + Memorial + Amnesia (Took a lot of trial and error to get the timing in this cutscene right.)
Roxas' Return + Hearts as One: RUN AWAY -DEATH MARCH- (Due to track being split into two audio files as well as the game's handling of said files, this was by far the hardest part to mod.)

Results: Carpe Diem (The ending theme for the anime)

Battlegates (basically tracks I couldn't find an appropriate spot for, but wanted to mod anyway.)
Hybrid -NEO Mix-
TATAKAI (I ended up making a version of this for Data Dark Riku, as I felt the lyrics suited Riku well.)
