Thanks, I was going to make that analogy. Somehow, you can always tell when a compositor (or a band of them) hasn't explored music enough to develop their taste; and no, I don't mean that they should make ridiculous "music" like Jacob Collier's, but it does show in other ways, like a childish focus on virtuosity and improvisation.

Very similar to those "I'm making my own language with blackjack and hookers" announcements where it's obvious that the author has only known the Algol family (Python, JS, C/C++/C#/Java and maybe a bit of ML flavour through Rust or TS) without exploring the other ways of thinking (https://madhadron.com/programming/seven_ur_languages.html).
