I don't listen to very much music, do Rdio and Spotify get the new albums as soon as they are released? With movies and TV there is usually a very long waiting period before they appear on Netflix and Amazon Prime. I'm not sure what a subscription service would cost that had all of the newly released movies but I'm pretty sure it's more than any person would be willing to spend.
Rdio and Spotify do typically get albums the day they are released (assuming the appropriate contract is already in place with the artist and label).
Movies and TV shows are completely different beasts. For Movies, you typically can only see them in Theaters long before buying, renting, netflix, pay-per-view, etc. TV shows aren't available until after their broadcast date, and sometimes not until months later. And the completeness of the catalog for TV shows on hulu/netflix/etc is EXTREMELY thin compared to the music catalog of Rdio/Spotify; even if you only consider current TV shows.
