 This occurs in real time. It doesn't matter whether the song is on the radio or if you pull up a drum and a guitar solo out of nowhere, making it up as you go along. I can go along with it with surgical precision mess-ups and all in real time. Wrap your heads around that one. I still am trying to find another account of this happening in modern time or history and have yet to find a single one. I have no prior experience with an instrument, no interest in music even,
