Daniel Rosenfeld

Daniel Rosenfeld, also known as C418 is credited as the producer of the music in Minecraft. He produced the world music, the ambience music and the songs for all 11 Music Discs. He also produced the various sound effects for the game, such as footsteps, and released the game's official soundtrack, "Minecraft - Volume Alpha", which includes all the music present in the game made by him up to the soundtrack's release, plus some bonus tracks.

Music included in Minecraft
(NOTE: As of March 4th 2011, Minecraft's tracks have been given "official" names)

Please note, these tracks have been shortened to 30 seconds on the wiki, due to an agreement with the author to allow them onto the wiki. This does not apply to "11".

Future
More music by C418 will be added in Minecraft in the near future. This will include music specific to battles, the Nether, The End, NPC villages, Creative Mode, and many more.

Released Minecraft soundtracks

 * Minecraft - Volume Alpha (04 March, 2011)

Cat
C418 revealed in an AMA on Reddit that the Ghast sounds are taken from his pet cat, and he makes those sounds when he is disturbed while sleeping. He was also going to have his cat voice Ocelots,, but since his cat never meows clearly,  , C418 decided to use cat sounds from Freesound instead.

Where are we now
As you may know, C418 - Where are we now - was intended to be in the game but was left out due to processing problems. However, with research I have managed to find out that Where are we now was implemented into the game but cannot be played without the Sound Pack mod. With it you will find out that where are we now is in fact the music for the title page of minecraft.
