Comments: This is a demo tape that came with Sony’s cassette tape player. It seems to be an accessory of Walkman’s first model “WM-20” released in 1983. Most of the demo tapes that came with cassette tape recorders at the time had music for audition recorded on side A and a blank side on side B for test recording, but this product is a playback-only product. Because it is a demo tape, music for audition is recorded on both sides A and B. The recorded music is all instrumental of pop songs that were popular at the time.
