I have a degree in economics.

Recorded music just like isn't a commodity. It's not close.

In fact, if you took a spectrum of all mass consumer products and ranked them from most like a commodity to least like a commodity recorded music would probably be on the side of least like a commodity.

It's not really an argument. Recorded music is not "kind of like" a commodity. There are tens of millions of recorded songs and literally every different iteration is wildly different, people consider some of them literal core elements of what gives their life meaning while other examples of the exact same product they have a visceral and intense hatred for.
