Correct, the main selling point for music streaming services is about having one place where you can find all your favourite music. It’s acceptable if you don’t find all the Star Wars stuff on Netflix - you can either watch other shows or movies instead or subsribe to Disney until you’ve seen it all, but a music streaming service with only the content of one or two major labels would probably be less attractive for many people, because they would only get a limited amount of music / artists. Also for the record companies it could mean higher cost (for maIntaining their own streaming service) and potentially lower profits.
