A device that controls background music interspersed with commercial
messages by using an unmodified Compact Disc (CD) player loaded with
custom discs. The custom discs provide the music and commercial content,
and inform the device of the rate at which the commercial messages should
interrupt the music. Dual Tone Multi Frequency (DTMF) signals are employed
to provide control signals to the device to inform it of the disc type,
track end, and rate of interspersion of commercial messages. The CD player
is controlled by either a wired or wireless remote.
