The system for repeating the selected music consists of a music selecting cct. (10) including a driving TR (Q1) for a solenoid (SO1') , a clock driving CCT. (20) including a driving TR (Q2) for solenoid (SO1), a control CCT. (60) including gates (G1-7) for comparing outputs of ring counters (50,45), and a reset CCT. (30) for reseting the clock timer (12), and ring counters (50, 45) with the output of the control CCT. (30).
