I see people calling for an all-in-one service for movies & TV shows, but that isn't likely to happen since the licensing and pay distribution for those work on a much different scale than music. A big reason is that in most cases at least 100x the amount of people will work on any professional video broadcast media as compared to a music album. It will continue to hinder consumer convenience, and the only halfway solution is the stream hardware giants giving you a unified interface to pick any piece of content you want and then display where it's available.
