I also am often kept awake by my brain playing songs, wishing my brain would stop.
A friend of mine spent about a month very focused on the aphantasia discourse, polling everyone he knew about little details. It forced me to consider it a bit as well, but I never quite landed on an understanding of how much a person's exposure/experience is a factor, versus what is (assumed to be) innate or genetic.
Where it was most interesting was when he asked whether I could imagine music or a song. In that area, I seemed to have a more realistic imaginary experience than any of the friends he had surveyed. I am classically trained in music (and ultimately am not very skilled), so I wonder to what degree I would have this level of clarity with recalling sounds, or even imagining new sounds or songs, if I had not been trained for years in music.
In the right circumstances and frame of mind, symphonies or sometimes brass band tunes play in my head, multilayered and everything. They've even got enough persistence that I can "rewind" them a few seconds (probably within some kind of working-memory window), even isolate parts of them and usually know exactly what instrument is playing it, and so on, then let them continue. The course of them is automatic, I don't control them, though.
If I had the first clue how to record them, perhaps I'd have a career as a composer, LOL. The actual invention of them would be no work whatsoever, though the writing it down would be, and I'm sure there'd be a good deal of editing and arranging afterwards to fix them up (plus, who's to say if they'd be any good, or wouldn't all sound kinda the same, to a trained ear?)
I'm only barely familiar with the body of "classical" music, and even less familiar with big-band or brass band music, is the oddest part, but those couple narrow sorts of instrumental music are all I get without having to put effort into it (and I mean none, it just "plays" when I'm in the right head-space and surroundings, and no I don't mean "on drugs", and actually it can be really fucking annoying if I'm trying to sleep). I wouldn't be surprised if I actually lost that ability (such as it is) if I tried to train up enough to write the tunes down.
... maybe I should look into humming-to-MIDI software, hahaha.
