Yes, i don't think the original content strategy will work out for streaming sites the way it has for netflix and amazon. I'm not willing to open one app to listen to one album and then another app to listen to a different album. I'll use the service that has all the music i want to listen to. Whether that's piracy or youtube playlists or spotify. If any streaming service starts getting too many exclusives, it's going to just kill the entire streaming market.
From my perspective, all the streaming services should be working together to create a healthy marketplace for independent music, and providing every opportunity they can for musicians to avoid signing a big-four contract. If Warner and Sony, and UMG get their act together and create a joint venture streaming service that's the exclusive host of the content they own, Spotify, Google Music, and Apple Music are screwed.
