SIRI is doing just fine without the cheapskate freeloader demo. SIRI has exclusive content and their own internet streaming service and it's way better than a glorified, random playlist generating jukebox. I have more songs in my personal library of music that Pandora offers.
Actually, I believe it would make sense. I have Siri, and Pandora, and Iphone, and wouldn't trade Pandora for any of them. You guys better accept it is a great concept, more user friendly than any of the media services, and will be around a long time.
