I recall the cassette days very well. Now we refer to that post-TT pre-CD period as the Dark Age of Audio. It was horrendous, especially for that poor Driver's Ed lady who taught me to drive in '79. She had made the huge mistake of allowing me to bring my own tapes to road practice, and soon we had every pedestrian in town made aware of our imminent passing through their neighborhood with that black Mercury Monarch blasting Nazareth, BTO (especially BTO perfect as loud road music for a 16-year-old driver-in-training lol), Nugent, Molly Hatchet, Rush (remember 2112 y'all?) et al. out of its windows with booming sub-bass oomph banging and shaking the whole street going
BOOM!-BOOM!-BOOM! from the trunk that could be heard half a mile away I was told.
Unfortunately that privilege of mine was revoked as soon as Dad heard (about) my disturbing the peace of that sleepy Maryland suburb. That slug of a car had a surprisingly powerful Pioneer sound system in it (to go along with the surprisingly weak engine I suppose), which seemed atypical for a DE vehicle fleet unit. I later learned that the driving school was procuring cars purchasing them from Avis Rent-a-Car and some other car rental outfit and that was the reason why some had such cool options. The Dark Age wasn't so dark after all
