It boils down to economics.
Why did rap become so popular? Because it’s cheap to produce.
I remember when Fleetwood Mac did “Tush”, I remember they spent at least a million dollars in studio time.
A rap record can be done for a fraction of the cost, and the “artists” are disposable.
“Tush” = “Tusk” (must have had ZZ Top on the brain)
No talent necessary either.
They often dispose of each other.
