Thanks for the follow-up.
What you describe above is pretty much what I call limbic-level listening. I am not aware of the limbic area of the brain as associated to memory or music memory, but then I am not an expert there. If emotion drops out in the meditative state you describe then that is what prompted my question. Limbic listening can include emotion to my understanding, but no need to quibble.
Here is part of what I wrote in a review under the heading:
Reviewer brain versus paleomammalian brain
...
"If you ask him about assessing sound quality, Vladimir will tell you first that "It is important . . to know how the real orchestra sounds. We choose a reference point based on live music and compare to this point," then, once so prepared, "the problem of sound-quality assessment is almost completely solved in the first 10-15 seconds of listening at the intuitive level."
The experience we have listening to music at that "intuitive level" is rooted in primitive limbic functions of awareness -- deep in our lizard brain. McGill University scientists observed that consonance and dissonance will light up the limbic systems responsible for pleasurable and negative emotions appropriately. The non-cognitive experience of music can trigger areas in the brain sufficient to cause the release of endorphins; when they reach the limbic system’s opioid receptors, feelings of satisfaction ensue. In his book "What to Listen for in Music", American composer Aaron Copland talks about this in different terms, describing how a fundamental aspect of enjoying music takes place on a "sensuous plane," which is "a kind of brainless but attractive state of mind [that] is engendered by the mere sound appeal of music."
If a component or a system breaks the fundamental rules of human hearing, our music-listening brain reaches a kind of tipping point where processing of music occurs less in limbic areas and more in the cerebral cortex. If my ear/brain system detects distortion, for example an excess of third-order harmonics that cause increased loudness or forwardness from that trumpet section over there in right field, in an instant it can happen: focus is triggered, the eyes open and the non-inferential immediacy of our musical enjoyment collapses."
Strictly the so-called 'lizard brain' is the limbic cortex, and is not where meditative function occurs - or so I read. Perhaps the anatomy is not so much the point. I think we understand each other.
