From 5 years old was taught classical music on piano. Then got into the Beatles, the Stones, Cream and all that. You are right we are different how we perceive and interpret.
Dunno dopamine, but years ago it was attributed to an endorphin release. Is that the same thing?
I understand that some jam bands used to rehearse material that had been known to give audience and band members that musical high. I’ve felt it a few times. Once at an Allman Bros encore of One Way Put at RFK with the Dead, and another time during a rehearsal, the sound msn caught it on tape but the replay didn’t repeat the experience. Maybe it has something to do with physical sound waves and the inner ear.
