Well in the 1970's records were cool because it was the main format for music they didn't have CD's, iPhones, streaming, like they do now. Their was records, tape, and live.
I have been buying vinyl since I was a teen, mostly new, until about 20 years ago. There was a time when buying new was pretty difficult unless you lived in a large city or mail order catalogue. For a while it was CD's mostly new for me, but I always had a turntable for all my records that I owned. I would buy used records at garage sales, and thrifts until the internet became a useful source. For a while when records were almost being given away and up until about two years ago, I would buy a lot of used both records and CD's. as they were cheap. Now I don't buy many CD's and the number of record buys has decreased due to the supply has slowed down. Now I mostly buy new records or select used records from Discogs, which varies from month to month. I am a hopeless romantic and like the finer things of the past, so records are played quite often, but I do love the sound of a good CD as classical music is very dynamic and with no surface noise a CD is really good, and the bass is IMO far better with digital sources.
