Abstract

A music playing system includes a number of music playback units with playback changer devices, coding units, and ISDN cards. Each of the music playback units is provided with playable pieces of music. There is at least one input unit by means of which the pieces of music to be played on a playback unit are selected. In addition, there is a central computer with a memory in at least one playback unit, with the memory storing data about the pieces of music available in the playback units. The playback units can be connected between themselves and to the central computer via remote data transmission lines.
