I mostly bought 45's, as they could be had for $.99. Albums were $12 or so.
I think the first album I did buy was The Monkees. I'd play it over and over and drive my parents nuts.
First album won from a radio station call-in was Manfred Mann's Earth Band, Nightingales and Bombers.
It included a track from a British Ornithologist who was recording the songs of Nightingales during WWII, when a squadron of bombers flew overhead. Don't know if they were American or German.
My daughter "borrowed" all my vinyl when she moved out.
Had lots of cassettes, but they didn't last. First CD I bought was Dire Straits, Brothers in Arms.
