Concentration

@rvpiano -- In my case, yes. I know others who are more interested in sonic details. While I can appreciate those, I am much more interested in what the musicians might be trying to communicate, and that doesn’t come through if I’m doing puzzles or reading a book at the same time.

Your analogy is interesting but I don’t think it really works.  We’re talking about a much more complex situation regarding SQ and music.  While it is true we listen to music and sound at the same time, It’s the priority that we give to each that’s the issue. Audiophiles tend to separate the two because of the nature of the hobby. The population at large doesn’t really care about the fine points of sound, so for them the problem seldom exists.its this separation that causes the problem in us. I believe that it’s difficult for us to ignore the sound component as a separate entity.

There are many different ways and contexts and purposes listening to music, it has many different roles - but none make me "doubt" my system...

Reading, doing chores, or writing something ... really lessens your enjoyment and can potentially cause you to doubt the quality of your system.  
What do you think?

I disagree. If I listened to my system only when I can give it full, undivided attention I would be listening 20 or 30 minutes a day, as opposed to 5 or 6 or 7 hours. So, far from lessening my enjoyment, ancillary activities greatly multiply it.
