The "endgame" would have to include something that Napster had, and spotify etc don't: guaranteed, unlimited, non-regulated access to everything from everywhere, any time.

I recognize that is the ideal spotify is striving for, and they're on the right trajectory. But they rest within the boundaries set by (inter)national copyright law, and that just goes counter to some of those features.

In that sense, we may be in an endgame-like situation, but I don't see this game being over before copyright is severely reformed or just outright destroyed by technological means.
