A playback system for a multitrack prerecorded tape cartridge or cassette includes a tape playback adapter for inserting the cartridge or cassette therein. The adapter includes a motor for driving the tape, a magnetic head for picking up audio signals from the tape, a switch for selecting a particular track, an audio amplifier to amplify the picked-up audio signals, a tunable radiofrequency oscillator for generating a carrier, and a modulator for modulating the audio signals on the oscillator. The modulator is connectable via a selector switch to the radiofrequency input terminal of an amplitude or frequency modulated radio broadcast receiver. A radiofrequency antenna is also connectable to the radiofrequency input terminal via the selector switch. Both radio receiver and adapter are energized by a battery power supply connected to both the adapter and radio receiver.
