We would still be recording music on these.
I miss those days actually. I would listen to songs played on the radio..played over..and over...and over...and over...and over... and over
If I hadn't gotten to the point where I'd puke on the dashboard before I could change the radio station, I'd purchase the LP in my semi-annual trip to the record store. (the disco years were brutal, thank God for Aerosmith and Lynyrd Skynyrd)
I still have most of my old LPs. Most were only played once or twice. All were recorded to high quality cassettes for rebroadcast via the tape deck in my mean little '68 bug.
I still maintain that the sound from an LP played on a good turntable blows a CD and certainly an MP3 away. Saturating a high quality tape by closely monitoring the equalizer during recording runs a close second.
And, I could run the cassette to death and make another from the once played LP when it went teats up.
