When CD's came in, I was astonished at how quickly
they swept away vinyl -

As a matter of fact, when CDs came in, it was cassette tapes that they
swept away. Cassettes had been out-selling LPs for several years before
the arrival of CDs. AM stereo sounded as good as, or better than, your
typical cassette tape, to my ears. There's no accounting for popular
tastes!
