Number Radio Stations

Imagine for a moment that you are listening to the radio. The station you chose originally isn’t interesting you at the moment, so you start searching for another to listen to. This is when you hear it…a sequence of musical notes. Then a voice comes on. The voice has been altered so you can’t tell if it is a male, female, or a child. They start reading a series of what seems to be random numbers over and over again.
