Back in high school (so, early 90’s) I had a Walkman with an auto-reverse feature. And then I dropped it on the sidewalk, and it broke, but in a very interesting way. It would still auto-reverse, but it wouldn’t change the side of the cassette, which meant that it would play one side of the cassette backwards.
This came as quite a surprise, but it was actually kind of cool, because around this time bands had started intentionally putting in backwards messages in songs as a means of making fun of the whole “OMG SATAN!” morale panic. One album (I can’t remember who now) had a recipe for cornbread hidden backwards across several songs.
