New music doesn't play for nether/oceans in current beta's.

The new nether music, aquatic music and Pigstep doesn't play on android and possibly IOS to my knowledge, When it does on other beta platforms like Xbox one and windows 10, when you do enter the oceans, already playing background music cuts of and nothing plays in its place and in the nether old music plays in the new biomes with no presence of the new music
