select/toggle music tracks

There should be an option in the UI to enable/disable certain songs/tracks for Minecraft. Personally I hate the new songs, only serving as another reason to not play the game, I prefer the original C418 track. 

This could also tie in with the potential for new songs/tracks on the marketplace! like in the avatar creator, there could be a section for community or official tracks to be published. This will make the game appealing to more people, as they can each make Minecraft their own personally enjoyable experience!

(apologies if this has already been added, but i extended to a potential marketplace idea!)
