8 technology revolutions that are now relics: Eight-track
Didn't some of the songs cut off in the middle and continue on other tracks? I thought we had one like that from Grand Funk Railroad. Ridiculous. And if the player ate them , I think they were unsalvageable. (you'd lose a couple songs on cassette)
Remember that charming k-THUNK that careless 8-track producers would put mid-song as it would shift from one pair of tracks to the next? It was either that or a bunch of dead air, neither choice very good. I had a pretty big stack of the things though. Dumped about 250 of them at a yard sale a few years ago. Allman bros to Led Zepplin, all for I think $30.
