The difference is that music streaming services actually offer a better experience to most people compared to movie/tv show streaming services for example.

Choose whatever music streaming service you prefer and you get pretty much the same huge selection of songs across the board. You can pick based on features and user experience. With movies and tv shows, most content is exclusive to a single platform. So you have to keep adding/removing subscriptions unless you want to pay north of $100 a month to have all of them at the same time. Every streaming app has a different interface and different features, and some might not work on all your devices. Piracy isn’t only cheaper in this case, but actually more convenient. It’s the better product, even when you leave pricing out of the equation.

Sure, some people will always resort to piracy, but there’s a direct correlation between the quality of service offered and the amount of piracy.

I can completely understand tv content piracy for convenience alone (and sure, it’s cheaper/almost free, that’s definitely a factor), but I never even thought about replacing music streaming with pirated content, because it’s just super convenient.
