 This happened only to me with all of my friends watching as we were listening to live music. I had no clue what was happening except that I was essentially reading the minds of the musicians and could play exactly what they were playing at the exact time all simultaneously. Not by hearing it once and then playing it from memory. 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
