I'm in favor of being able to pay to access a library containing 99% of titles in existence, even though i don't "own" permanent access to them. If i had to pay a higher price to "own" each individual title then i would have access to VASTLY less media. But for that monthly payment it must offer access to 99% of titles in existence, and the price must be reasonable for the amount of entertainment value i actually derive from it. Spotify is a perfect example of a 99% complete library at a reasonable price. And yeah as you point out, the service must be available on all devices, like Spotify is.
