Steps to Reproduce

Open Minecraft, and (this has only happened once, out of the many times I opened the game) it rarely will play both menu musics.

What You Expect To Happen

I expected for only the Aether menu music to play

What Actually Happened

Both menu musics played

Additional Details

This could be caused by my addon's music manager, but it's unlikely (and could probably happen normally also) since it doesn't change how the menu music works at all.
