Music: you can find nearly any song you want on Spotify etc. so you don't need to have multiple services, and the context creators get paid for your listens, which seems like a win for everyone, and it's way easier than pirating and also affordable to there is little motivation to pirate.

Movies/TV: you never know what shows are on what platforms without background knowledge, you can't just buy one and trust that nearly everything is on it, so you are incentivized to pirate (which is actually less work) and no one gets paid and it's kind of a pain for the end user also.
