Morning!
So I’m following more of a regular sleep schedule than I intended.
Anyway, a good night’s rest helped me figure out my sound issue. You can’t play multiple Music(s) at once! That was throwing me off. So I swapped out all but one of my musics for Sound(s) and that should make it so i don’t have overlap. Unfortunately, that now means I can’t use the fade function anymore 
Here’s a screenshot!

That’s unfortunate man, but your work looks great
