As I am still getting my new system up to it’s potential, it’s about 90% sound quality, now.
The goal is to switch that over to much more music listening.
But for me, the hobby of being an audiophile means taking an active role in making my system sound good, testing it for differences, adjusting it to see what happens. Part of the fun of being an audiophile is that experimental activity.
And a huge part of what’s been of value in listening for SQ is, as Millercarbon says, that I am learning how to listen. That feeds back BOTH into (a) listening for SQ and (b) listening to music. Without listening for SQ at least some of the time, I stop learning how to listen better.
In other words, listening for sound quality is a permanent and legitimate part of what I am doing. The percent of how much I’ll do either remains TBD, but the idea that this hobby is "just about the music" is laughable, for me. I love sound, I love experimenting, and so the music is never going to be the only goal.
That said, I understand why it could be a worry that one is not listening to *enough* music. The "grass could always be greener" compulsion can be like quicksand, and the question of how to avoid it is a very personal, psychological question that reaches deeper into our drives and needs than can be answered by questions bracketed at the level of audio.
