Gotta beat. How about 4-track tapes?
“How about 4-track tapes?”
Nope... unless you’re referring to reel-to-reel tapes which I did “play” with. First time I heard Joe Walsh with the James Gang.
My dad bought a new 1967 Mercury Cougar that had a 4-track player. He was pretty annoyed when 8-tracks came out shortly thereafter.
Last time I saw 8-tracks for sale was in 1988, at a truck stop in Wells, NV.
