Did you know that you can build a Jukebox that will actually play music in your home? Well, it will play music once you actually obtain some of the Music Discs that are available as loot in the game that is... The Discs are obtained either by luring a Creeper into a position to be killed by a Skeleton's Arrow (which can spawn a Music Disc as a drop), and as rare loot in dungeon Treasure Chests.
Each Disc plays original music that was composed by a player named "C418" (Daniel Rosenfeld). In addition to producing the music for the Discs, C418 is also credited with producing many of the sound effects as well.
At the present time there are a total of 11 Music Discs in the game -- and some are considered more desirable than others -- but none are really rare since they are mostly a random drop and you have about as much chance of getting one as another for most of them. There are exceptions to this, though they mostly apply to Disc 11 and variations of Discs.
Discs 13 and cat are found in roughly 8% of dungeon chests, and are also dropped when a Creeper is killed by a Skeleton's arrow. All of the discs except for 11 can be obtained in dungeons, strongholds and dropped by Creepers killed by Skeletons.
The following Discs appear in the game:
-- 11 -- The contents of Disc 11 is not music, but is a collection of sound effects including a person running over different block types and other actions.
-- 13 -- Another Disc that contains sounds rather than music, though mostly the sounds on this Disc are mechanical in nature.
-- cat -- An upbeat synthetic melody.
-- blocks -- An upbeat melody.
-- chirp -- An upbeat melody.
-- far -- A calm and relaxing melody.
-- mall -- A calm and relaxing melody.
-- mellohi -- A slow, creepy guitar piece.
-- stal -- A very cool jazz piece (widely considered to be the best Disc in the game to find).
-- strad -- A reggae tune.
-- ward -- Chopin's Funeral March.
