But why Spotify and why now? Couldn't they have hit Apple, Real, Microsoft, (new) Napster, Amazon, Pandora, Last.fm and a zillion other drm-music-to-device streaming services before now? Have they summonsed these services already but we just don't know about it? Who exactly is trying to keep Spotify out?
Spotify is just getting established in the US market, so they might be particularly attractive, weak prey that can be easily killed in order to establish a precedent.
