Once upon a time, back in Russia we had a service that captured most of FM radio stations and detected what was playing real-time as you listened from Moscow to some obscure station 2000 km away. Sadly it was all trampled by copyright idiots by about 2013.
But the technology, the capture boxes which were SDRs before SDRs were a thing, hashes, station bosses calling in the night because DJs got too drunk and went rogue live.. oh the memories..
