> I would find it genuinely sad to talk to a musician about their arrangement/composition choices, only to find they couldn't

So much of music composition is what "feels right" and is instinctual. Artists aren't consciously aware of probably most of their influences. They can cite some of the most obvious ones, but the creative process is melding a thousand different vibes and sounds and sequences you've heard before, internalized, and joined into something new, in a way only your particular brain could.

Let music historians work on trying to cite and trace influences. That's not something artists need to worry about.
