If you enable this mod and then load a game that didn't have it active while you saved it, it will break the menus music and it will continue playing indefinitely.
----
To fix this, go to "Load" then click on your save file.
In bottom right corner click on "More.." then "Chose Mods.."
and here enable this mod.
Disable any other mods that change menu/music.
After that go back and load your game normally.
