There's a terrible overlap in music in-game that occurs when someone enters a new area. Instead of each track being played when you're in a specific location, they're muted ever so slightly in the background instead. This doesn't work, as overtime more and more audio tracks stack making the music so very annoying to deal with.

You could propose I play with my music volume at 0, which most of the time I do, but the music in Era is admittedly pretty good and the only thing causing me to play mute is this side effect of actually trying to play otherwise.

Here's a video presenting what I'm talking about. Listen closely, you'll hear it. https://youtu.be/a2VlTwB1Unk
