Music production costs are much much lower than TV/Movies.
The argument is that differentiation (and then exclusive content) is the reason why content distributors are willing to take risks.

Content distributors don't need to take risks. Theaters do a bit, because screens are limited. Stores do a tiny bit, because shelf space is limited. Online services don't have to at all. The producers take the big risks, but I don't see why that should imply that streaming services have to involve exclusivity agreements.
