This is a big one for me. I'm almost never home alone; throwing on music there would usually count as inconsiderate or exclusionary. I used to do a lot of listening in the car, but I do very little driving now. (Short commute, hybrid work at home schedule. And that tiny amount of bandwidth is often consumed listening to the news.) I don't multitask well, preferring to focus on whatever I'm doing, so I don't even bother trying to listen while I'm working. And post-kid/ post-COVID I only get out to see a show a couple of times a year.
Long story short: I'm a "musician" who almost never listens to music, unless it's to learn a part. It definitely exacerbates the whole "why?" struggle I described above. It can get pretty weird; I'll catch myself musing abstractly about what "songs" are or why they even exist.
(Meanwhile, it seems like all of my friends are deeply familiar with an incomprehensible glut of music I've never even heard of. I can't even imagine catching up at this point LOL.)
(But I know every conceivable detail about every single digital signal processor thingamabob I demonstrate absolutely no need to own...)
