A jukebox is a partially automated music-playing device, usually a coin-operated machine, that will play a patron's selection from self-contained media. The classic jukebox has buttons, with letters and numbers on them, which are used to select a specific record. Some may use Compact Discs instead. Disc changers are similar devices that are intended for home use, are small enough to fit in a shelf, may hold up to 400 discs, and allow discs to be easily removed, replaced, and inserted by the user.
