I don’t really see the point of this comparison. Composing, arranging, and producing a song is not a benchmark you can profile against; musicians are not performing some kind of music compute that produces a set number of music units per hour.
Speaking from my own experience, I’ve had tracks that took months to complete, and I’ve had tracks that I got to probably 90% completion in under an hour. I would propose that there’s no meaningful definition of “superhuman” for creative efforts.
Agreed. Although "professional" pop production does tend to be somewhat involved, it doesn't have to be, and total time spent could vary so radically as to have essentially no correlation to anything else.
