Abstract
A method for playing tunes from a plurality of disks stored in a magazine in random order and without repeating any one tune. Three memories are provided. In the first there are recorded the identities of disks which have already been played, in the second, the identities of already-played tune S on each disk, and, in the third, an incremental count of the number of already-played tunes on each disk. The tunes are selected in terms of random numbers limited by the number of as-yet-unplayed disks derived from the data stored in the first memory.
