Pocket Rockers

Pocket Rockers were a form of miniature audio cassette made by Fisher Price in the late 1980s and early 1990s which was briefly a youth craze, and like just about anything that becomes a youth craze it was banned by some uptight school administrators. Each Pocket Rocker tape (which could only be played in the Pocket Rocker player also made by Fisher Price) contained two songs, one on each side (you had to push a button to reverse the tape after listening to the song on one side), by such artists as Debbie Gibson, Tiffany, and Bananarama.
