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 cloak in survival multiplayer.
 * The songs '11' through 'Where are we now' are encoded and saved as .mus files in the minecraft/streaming folder. Although the game does not use them, it contains code to decode them.
 * His Minecraft skin is the default skin, but the head is replaced with a record player block.
 * As of 1.9 Pre-Release 2, there are 11 music discs, all containing original C418 songs.
