I don't think that's feasible for Spotify -- why would you subscribe to a paid monthly music streaming service if most of your music (the 85% produced by artists associated with the "big 4" labels) isn't on the service? Sounds like a good way to drive people back to piracy. Honestly, Netflix's selection is poor enough that I know quite a few people who have gone back to piracy. Spotify is in an even worse position.
