Maybe one day we'll get to the point where the content is mostly commoditized, and we'll simple be paying for whichever aggregating service provides the best usability (such as searching, recommendation, shared watching with remote friends, etc) will be leading instead. I don't think it will be anytime soon though.
One big difference is the production costs. Much cheaper to procedure two hour record that a block buster movie. And people are happy to consume the same music content over and over again. With movies and series most people won't do that.
I'm happy to pay extra for content from Disney or HBO, but I just want a consistent user experience. I was a single app that will let me access all of this content.
Except every channel on Roku is a different app with a different experience - Netflix, Amazon, Google Play, YouTube, ... all provide similar functionality, bit with differences in UI.
Just give me a best-of-breed UI that lets me watch all the things.
I just subscribed to HBO through Amazon for this reason. It's really great. Amazon user experience and streaming capabilities seem better than HBO. But HBO is the only place you can get Game of Thrones. Win-win :)
I think Kodi has a decent shot at getting there - there is now a fledgling Netflix plugin. A big step towards providing content to the major streaming services (and local content) through a customisable UI.
People pay 10-20 times that for cable. It surprises me when people commenting think no one will pay for multiple services. Sure you will, but which ones will make the cut?
Spotify also doesn't pay the artists enough for most of them to survive. Studios know this. They know that $10/month isn't enough to support the creation of all the original content that has been supported in the past by $100/month.
I have a hunch that studios will find a way to pocket about the same amount of money that Spotify already does. Just based on the reports of how they treat non-superstar artists already with hollywood acounting [0].
They want more money for the studio to survive, not artists. Artists are probably "a dime a dozen", and possible to manufacture from a studios perspective.
It is more than I ever spent on music before though (not a pirate, just didn't buy much music.)
Same with netflix.
I'll not be happy with paying monthly for n different channels to watch a film.
I want to pay. But either one service with all I need like Spotify or paying for the stiff I actually watch.
