(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.

Trivia

 * In-game music is cued by the time of day, with a random track being played at sunrise, sunset, noon and midnight.
 * Like Mojang employees, his in-game character can be seen wearing a cape in survival multiplayer.
 * His Minecraft skin is the default skin, but the head is replaced with the texture for a jukebox.
 * As of 1.9 Pre-Release 2, there are 11 music discs, all containing original C418 songs.
 * These include all of the previously-encoded files except 'Where are we now', due to troubles encountered when adding in music with spaces in the name.
