Out of tune music - Mac

[Wardie]

Has anyone else noticed that some of the music plays out of tune?
It's as if one or two of the instruments are playing in a different key...

The first time I noticed it was when I was in a tavern, and I thought, "Cool! They've made the music sound drunk" but then I also noticed it in Qeynos town, Kelethin etc.

I am playing green server on a macOS Sierra - is there a way to edit the music files? Or perhaps replace them.
