Music tracks play on top of each other

One music track will start playing, and then another one will start before the first one finishes. This has happened to me on the main menu (A lot on the main menu) and creative, but not survival, (yet) although there have been reports of it happening in the nether too. (Which I haven't tried yet) It sounds horrible and I really like the new music, but I can't enjoy it because of this.
