However, without some sort of understanding random noise, and that random
noise can exist in a picture, there is no motivation to take the un-obvious
measures (e.g. averaging over many frames, clipping peaks, etc) to remove
it. Then, after filtration, subsequent analysis must understand that the
result comes from a signal processing process that may distort details, so
that decisions should NOT be made on the basis of small details.

I have also made this same point in the past. There are many excellent
compositions where a repeating theme has more and more complications added
to it.

BTW, my very first computer program (on an old electromechanical Burroughs
E-101) composed rock-n-roll music.

YES. I also suspect that some of the best pieces that are "on the edge" of
this, where some people can follow this process but others can't, and/or
where you seem driven to hear the piece over and over to "understand" ever
more of its nuances.
