true, music is never a metric for analysis and design of audio gears, we use sine waves instead...
how do you use music as a metric? what if you play loud? what if you play soft? what if you move 10 meters away? what if you come closer? what is you change the tracks in the music? how do you measure all that? what is the standard? what is you use tube amplifiers? what if you use solid-state amps? what if you use a wall of sound speakers? what is you use a 3" FR speaker?
.
millions and millions of variables, permutations, how do we begin?
IDK, I’ve found that music can be a valid test signal. How does it sound at normal volumes? How loud will it play before distortion is perceived? How loud before it becomes objectional/intolerable? How loud (and long) before something you’d rather not happen, happens? Extended high power testing doesn’t necessarily require listening at that volume. Could be just run it into a dummy load and leave it cranked for a few hours. The “sound quality” can be monitored by tapping off at line level - all while monitoring the scope for signs of the amp misbehaving.… and the temperature.
I have found that the results correlate very well with how it measures with a sine wave (which may be a clipped one- a very clipped one). But with the music signal it will always run longer before “something happens”, and you get an idea how long it can be run in actual hard use.

There is absolutely 10000 reasons to use CD transport these days and one of the reason is a respect to an artist. You get your fat, lazy *** of the couch and change cd in the player.
It's always a metric, just not the only metric. Discarding the very purpose of music systems as useful for validating music systems seems extreme.
my local library of flac files is largely there to keep me seated so I can increase the sheer size of my fat ***. What is this talk of exercise just to listen? if I wanted to get in shape I'd just take up smoking.

According to dictionary "metric" is a standard of measurement. So music as such is not really a metric for analysis. However music can be used as a test signal for difference analysis or null testing. Have not seen much of that here. Of course music can be used for determining subjective preference but that is not a metric.
I was surprised to see that. Another convert, it would seem.
...which reminds me of this:

What if the artist originally recorded onto 24 track tape and released on vinyl? How does a CD respect that?
The trouble with music-as-a-metric is that it brings a lot of subjectivity into it. As in, if I hate the music you are using, I'm not going to notice anything, but if I use music I know and love, I might. So any results are not easily transferrable.
To the contrary, the goal should be design by discrimination of performance, not preference. IME the music we use is not particularly liked by me, never did like it and by now I'm kind of sick of it. Its selected because it has certain attributes that makes it useful for evaluating several aspects of system performance. And we do notice a lot. IOW that type of listening is to do work, not for pleasure.

If you use listening tests for discrimination of performance why do you use phrases such as "sounds better" or "sounds best"?
AFAIK you have never reported any results from these so called discrimination tests, only preference. And that probably more often than anybody else on this forum. If the end result is your subjective preference then the real goal of the test is preference, not discrimination.
False. A well performing system should not make music played for pleasure sound bad. You seem to forget there is no such thing as transparent reproduction of music. Doesn't matter how pleasurable a nice looking FFT is for you. You builds may still sound poor if all you do measure for numbers that do not and cannot assure transparency.
I will stop here for now.
