And Netflix also will have the same problem. Streaming will just be a feature for a company like Disney. By the time a Marvel movie for instance gets to streaming, its already made hundreds of millions of dollars from theatrical releases, dvd sales, VOD, etc. The streaming service doesn’t have to be self sustaining.
Netflix is also struggling under a heavy debt load and is still not consistently profitable.
If any of the major record labels leave Spotify - they are toast. Especially if all four labels stay on a competing service. People are okay with getting thier movies - that they will probably only watch once from different places. No one wants to have multiple playlists from different services.
The music industry already tried that. Before the days of iTunes there were two subscription streaming services - MusicNet and PressPlay. Each had two of the major labels. That failed miserably.
If an artist is exclusively on Spotify, they’ve lost exposure to much of the more affluent users who have iPhones and are more invested in the Apple ecosystem.
