I used to like to buy TDK tapes second hand and listen to the mixes. Almost every one had something obscure on it I loved but they have dried up over the last 12 months.
A few years ago I stopped at an estate sale in a small town I was passing through, far away from home. Picked up an 8-track player and a few dozen cartridges, the majority of which were mixes.
It was just fascinating to listen to. I’m pretty sure it was mostly obscure 1970s and 1980s country with the odd Blondie song thrown in here or there.
