"Spotify & Apple Music" --> Rhapsody/Napster already had this in 2001. I was a subscriber soon after. So many thought music subscriptions were a strange concept, from mainstream media to TWiT, and that it would never work. I think Rhapsody/Napster was too far ahead of its time, and faced too many technical obstacles, especially when they switched their DRM too many times (they eventually used one from Microsoft, forget the name, which Microsoft discontinued in favor of their own Zune service, and Rhapsody/Napster had to scramble). When Apple and Google jumped in, and Netflix showed the possibilities on the video side, Rhapsody/Napster already was stretched too thin to compete.
(Of course, the incarnation of Napster referenced here is very different from the original Napster concept.)

Yeah but neither of those had a billion+ smart phones to deliver their subscription service to. Not really their fault, but clearly mobile streaming was what really made this type of product skyrocket in popularity.
I don't know how much spotify & apple disrupts label's biz model, they still have to pay enormous amount of money to the labels for songs being played.
They supplement record label's core business more than they disrupt.

EDIT: Windows pre-Zune DRM was https://en.wikipedia.org/wiki/Microsoft_PlaysForSure (PlaysForSure) -- it was "anything but". So many synchronization problems with devices, it was painful.
