Music tracks layering/over each other.

Seems to keep playing in-game music after quiting to main screen, then
when back in game, the main screen music then continues, also switching to creative whilst in game can also cause the creative style music to play on top of the previous other 2 types of music from in game, and menu all together, have to completely quit out altogether to stop the layered tracks playing in order to stop the noise. Restarting the game always clears the music.
Switching between in-game and main menu screen a few times causes the music to layer on top of each other.
Only happened since 1.9.x
