Is this arguing that, in order to produce commercially valuable music, all music is conforming to a set of standards, or traits and conform to "a grid"? That's how I read it.

Does this (2019) article propose the opposite? That hit music usually contains a sort of pleasing surprise, and that over time our hits have to become more and more unpredictable musically?

That's now I'm reading it. But I'm a music consumer, not a music creator, so I may be missing some nuance or conflating related ideas.
