Cassettes were for collecting and trading Grateful Dead concerts. Did they have any other purpose? ;)
Every Dead Head I knew had at least a few tapes, many had 100s. When I went to college (late 70s), the people with the best Stereos (that's what we called them back then) were the Dead Heads, hands down. Most non-deadophiles had the all-in-one Panasonics, Sonys with the cheap turntable on top, cassette built in and radio with crap speakers hanging off the sides. But the Dead Heads had real 'stereos', separates with most of the money going into the cassette decks to make sure they could make the best copies.
