I don't normally mod games in general, but I want to mod the normally unused song Pizza Mayhem into The Crumbling Tower of Pizza as going for 101% will still not have the entirety of "Bye Bye There" playing in a speedrun attempt of CToP, while Pizza Mayhem will just barely hit its loop as it's only around 3.5 minutes long.

It'd just feel really cool if that was playing on a good run so I'm really hoping the answer is yes. The mod in question: https://gamebanana.com/sounds/66594
