I've had this one swim around in the sandbox for awhile, so I decided to paste this on here:
This article describes a D-C60 cassette tape (developed during 1979) that when played, it will orchestrate a random compilation of rock music (seven (7) to eight (8) tracks have been recorded to come on per recording) that are made in between the years of 1971-1989. When listened to, the user will experience strong visual hallucinations of what seem to follow what the song represents. But testing has shown results from a user's unaffected perspective, the listening subject seems to be in a trance state of relaxation. If forcefully removed from the influence of the tape, or one abruptly pauses its recording, the user will become agitated, and "beg" to listen to the cassette tape "for just a few more minutes". This, however, is never true:
Being exposed to the cassette tape's music multiple times, results in gradual deter of the human intelligence, rendering them soon to be only mindless subjects. After hearing the tape, Personnel are to go over a three (3) hour psychiatric evaluation, if results prove intelligence to still be in proper condition, they are pardoned. If results prove the subject's intelligence reaches below-average outcomes, they are to be immediately euthanized.
