I don't think it's DRM. When you subscribe to a music streaming service - you get 90+% of the music you'll ever need.

But you can't get the same subscription with movies/TV shows. You get a fraction of content with each subscription. When there will be a reasonably priced subscription for most of the video content - it will change the situation.

So in my opinion, it's not about DRM. It's about convenience.
