So I've discovered that this mod has an issue with Infernum Mode Music. Disabling that should allow tMusicplayer to run fine. I don't know why its an issue, and it sucks because Infernum music is amazing, but yeah.

That is a lot of mods. Can you list the ones that add music here?

If it is a Calamity add-on, its probably because they overwrite boss music which screws up how my system works. Though that's just a hunch, and I'm not sure if that is exactly what they do.

So I tested what RunningOffCaffience mentioned, disabled the Infernum Music Mod and that seemed to fix my issue, I haven't fully tested Calamities compatibility in general but at the moment, Infernum Music is a no go

I will try to get ahold of them and see if we can resolve the issue.

Hopefully this issue has been resolved in the latest update. I still haven't been able to get a hold of the Infernum devs, but my code should be more defensive now and prevent the error from occurring at the very least. Worst case scenario there will be missing music boxes.

The issue was unfortunately not fixed with the update. I am still looking into it for a solution.
