8 Creepiest Broadcasts Ever Caught On Tape

7. Backwards Music Station

Word of warning, the Backwards Music Station doesn't actually play any music, just a terrifying audio hellscape of jumbled frequencies, high pitched whining and startling grinding noises. It is also known as the Whalesong station as some people think it sounds like the haunting melodies of whales (spoiler, it doesn't).

The signal has been broadcasting intermittently for many years, occasionally firing up for a few rousing choruses of nightmarish whirring before going quiet for months or years at a time. The signal is thought to be coming from two different points, one in the US and one in the UK or mainland Europe. Theories as to what it could be have been flying around for as long as it has, with everything from secret encoded messages hidden in the feedback, to a message from Cthulhu himself.

Another surprisingly reasonable explanation for the BMS is that it is a back-up network for the military, kept in case the usual channels of communication go down or are compromised. They are supposedly fired up every now and again to check that they are still in working order, hence the intermittent bursts of transmission. Whatever it is, it's definitely not the kind of thing you'd want to hear trickling out of your radio in the middle of the night.
