If you don’t plan on reading the link above, here’s the summary: In the 70’s, a company pressed a series of records to be played on repeating turntables, such that when you, owner of said record, left the house, you could first put on this record, which itself contained hour-long improvised conversations. Theoretically, would-be burglars would hear the record playing, assume the place was occupied, and find another target.

My point is this:
There is something beautiful about a record which, in an optimal world, nobody would ever hear.
