Jukebox

The jukebox block was introduced in Minecraft Alpha version 1.0.14. Right clicking on a jukebox while a record is equipped will make it play music corresponding to the type of record you used; Right clicking on the jukebox again will stop the music and eject the record. There are currently two types of records that can be used on the jukebox. Sound from the Jukebox travels roughly 75 blocks.

For about an hour after the update, using the crafting recipe for the Jukebox would result in a bookcase.
