Yes, intellect and feeling can be discerned. Trouble is, they cannot once you start typing as you are always channeling the one through the other. The eternal problem of Albert Schweizer. Still he wrote some books that make sense.
Intellect is not an aspect of feeling. Feeling is not an aspect of intellect. Both are aspects of the person and intuition resides between and varies. For each person intuition reaches elseplace than for others. The very question on discerning between the aspects of feeling and intellect is rather nonsensical and though stale, yet somehow still sensational, but still silly in the end. Intuition cannot be parted, yet it is part feeling and part intellect. That does not mean there isn't pure intellect or pure feeling as well.
The notion that a dichotomy that discerns between the two aspects of discourse is false is plain silly. dialectically that is.
So there is no "depth" to be had in trying to discern these two aspects, every body does it all of the time, although not consciously (ain't life grand?). Maybe if you can place intuition in a valid common path of evolution through the times, there is depth to be reached. Good luck!
Saying that "today's musicians" are "intellectual (and emotional) in a much different way" does not really say anything if you do not tell how and where. And who too, BTW. It may turn out "they" have tilted their balance of feewing and tfought after all.
All of this has nothing to do with the discussion at hand BTW.
I have a sudden urge to talk about pudding, but I digress....
