ABSTRACT:
A prerecorded magnetic tape format having program breakpoint alignment is used in the present invention to provide continuous long duration, highly non-repetitive, program selectable selections of music as for use in background music systems. Cueing means are provided at the end of each set of recorded musical selections of a multi-channel playback system. The cueing signal is used to trigger a programmable channel selection means for controlling which channel of the multi-channel system is selected for reproducing the next recorded musical selection. This program breakpoint switching process is repeated for any desired playing interval.
