You can, but good luck because all the pops would make it sound really bad. I'm not sure whether WAV export works (press R to start recording and R again to stop) so if it does, you can use that audio sample. Otherwise, just use an audio recording program for it, like Audacity.

I usually feel somewhat the opposite (on the skill admiration thing). If you're not painting something interesting, your skills serve only as a surface level facade.
I dunno if i'm a beginner with PS itself, but certainly with various facets of art. I hadn't ever taken a good whack at landscapes/environments until like a month ago. I'd never painted faces with color a few months before that again.
Also, interesting that you were reminded of Stålenhag, that's the guy whose style i admire the most. I don't want to emulate him, but i'd like something in that ballpark.
