I am looking to make a mod for Pizza Tower that adds custom music for every level in Pizza Tower during the Noise's campaign. All the tutorials I've found on here so far have only gone over how to replace music (not add), which causes the music to change for both the Noise and Peppino- whereas I need it to only change for the Noise.

To put it more simply I need:

1.) Code for adding Noise campaign (ONLY) music - only level themes as it stands right now (also, how to code A+B music like Hot spaghetti/Cold spaghetti)
2.) Where to insert this code in UTMT or whatever modding tool I need to use
3.) How to export the mod and make it playable.

An example of what I want to do can be found in the noses video here: https://www.youtube.com/watch?v=nIDK6ZrI1Dc&t=215s&ab_channel=thenose

(Anyone who is willing to assist will, of course, receive due credit.)

I have FMOD installed and all of my audio files are .OGG and ready to set up, just somebody please help!
(please provide a step by step guide to how I should do this, and PLEASE explain the steps—I don't want to waste anybody's time by having to ask more questions ヽ(´ー｀)ﾉ )

Thanks in advance!
