Today's coincidence story is short but I don't remember ever hearing a similar. Thanks to JC for this.
"I was listening to a Killers album on CD one day, when I wandered into another room and switched on a radio.
The song playing on the radio was not only the same track (Mr Brightside), but the two songs were perfectly synchronized. I turned the radio volume up, and there was no discernible difference in timings. When there is a delay, even a slight one, it is very obvious to the listener.
It occurred to me that the radio must be acting as a speaker by some strange phenomenon, but then the song finished and my CD moved on to the next track while the radio DJ introduced another song."
