Music Disc

Music Discs (previously named Records) are items that can be played in jukeboxes. They play music made by C418. Despite the music files themselves being saved in a playable .ogg format, custom music cannot be used unless a modification is installed.

Acquiring discs
The music discs "13" and "cat" are found in 8% of dungeon chests. All music discs can be obtained by getting a creeper to be killed by a skeleton's arrow.

The player can achieve this by positioning a creeper between a skeleton and themselves, then attracting the skeleton's fire. Since 1.2, mobs no longer attack a second target unless their first target is either killed or out of range, meaning the creeper does not have to be a 1-shot-kill like before. Skeletons will only fire if they are within 8 blocks of the player, so it is recommended that you hunt with speed potions, and be ready to sprint away or sprint attack the creeper if it gets too close. Creepers have 20 health points, or 10 hearts, so it is recommended that you hit them three times with an iron sword (3 hearts damage), then attract a skeleton to one-shot-kill them. This also gives you a single chance to sprint-hit the creeper away if it gets too close. It is also recommended that you make the chase occur within either a plains or desert biome - or some other almost very flat land - so that you can look at the creeper and skeleton without having to look behind you for obstacles.

It is also possible to build a contraption capable of trapping the skeleton and creeper in such a way that the skeleton tries to shoot you through the creeper, but the creeper cannot attack the skeleton. A relatively simple design using pressure plates and pistons to trap the two mobs in their appropriate places is quite effective. Previous designs were typically based on luring each mob into a hole, however, these ceased to be effective with the upgraded mob AI.

Discs
''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".''

Raw music files
The 12 music tracks created for records by C418 can be found in:
 * Windows: %appdata%\.minecraft\resources\streaming\ (AppData is hidden by default)
 * Linux: ~/.minecraft/resources/streaming/ (.minecraft folder is hidden)
 * OSX: ~/Library/Application Support/minecraft/resources/streaming/ (~/Library is hidden in 10.7)

Of the 12, only "cat" and "13" are in a readable Ogg Vorbis format. The remaining .mus files are locked with a simple encryption algorithm. However, they can be decoded by Minecraft on the fly.

You can make the discs play your own music by replacing the .ogg files for "cat" and "13" with your own .ogg files.

Future
It has been stated that in the future, there will be 14 music discs to find in Minecraft, and the changelog for Beta 1.6 confirmed that the record player will support 'more than 15 songs.'

Trivia

 * One of the disc names, stal, is in Swedish; "stal" means "stole", but can also be "stål" without the ring diacritic, which means "steel".
 * Music disc "11", based on its data value, is the 11th disc in the game, is the only music disc that is shattered to pieces (proving the broken static at the end), and the length of the music is 1:11.
 * Chirp is an Optigan sample that is also used in the song Interludes with Ludes by Them Crooked Vultures and the opening to all the games in the LittleBigPlanet franchise. It sounds very similar to "The Orb Of Dreamers" in little big planet, but not exactly. You can compare the two here:
