Music

Music is a feature that may be added in a future update. It is in Minecraft Windows 10, Minecraft Console, and Minecraft PC.

Types
There are a two types of music coming to Minecraft PE:

Background Music
This theme plays in the background. This music may be the same music from the computer version, or it may be PE exclusive (speculation). It is simply called "Minecraft". The music changes into other various songs based on the player's location. (e.g. if the player in the Nether, the Nether theme will play)

Music Disc
Some music comes in the form of discs. They can be played in jukeboxes. These discs can be obtained through Dungeon Chests or when a Skeleton kills a Creeper. There are many music discs.

Disk 11 is the only disk that is cracked.

Trivia

 * Most of the music was composed by C418.
 * In other versions, every dimension has specific background music. The Overworld has "Minecraft" and the Nether has "Dead Voxel" and "Concrete Halls". The End has "The End."
 * Only two discs can be obtained through dungeons. These discs are "13" and "Cat".
 * There are two albums of Minecraft music- Minecraft Volume Beta and Minecraft Volume Alpha.
 * The 'Cat' music disc plays the soundtrack 'Dog' when used by a jukebox.
 * Music Disc 11 is different from the other disks because it is cracked and all of its data (and so on) all contains 1 or 11.
 * It is very unlikely to be added to MCPE since Tommaso stated that if music was added, it would use so much space Minecraft would be unplayable on older devices. But it has been suggested that Music will be an optional download.
