Netflix was great until everyone else caught up in the streaming war. Everyone else holds the licensing authority and they don’t give Netfli what they want. Plus, Netfix keeps killing their popular original content for reasons that fans don’t understand.
Music on the other hand is so strange and different. I knew the big 4 tried again and again in 2000s to offer form of music store but failed. Since none of the existing large music streaming services (YT. apple, Spotify) license, labels are happy to hand them licensing agreements.
