When music starts playing on an open world, a second track sometimes starts playing over top of the normal track. This second track will play continuously when the game is paused of if the world is closed (I.e on the main menu).

If the music volume is set to 0, no music can be heard. However when turned back up, the normal music will have stopped but the 2nd track will continue to play.
