And what comes to streaming the songs you've bought, why bother paying $25 a year for that? Just get Spotify or rdio and you can stream any song you like. No need to pay for the songs you want to stream.
Sorry, but this is useless service. The competitors have done it better and cheaper and there is no use for this when you can just get a real streaming service and get access to millions of songs right away. Hell, even Zune for Windows Phone 7 has such a streaming service and it's far better than what Google is trying to offer here.
