I don't think this will take off as well as iTunes has so far. Though, I do hope it forces Apple to step up its game and offer a subscription service for its music.

Gorgeous software, but it feels like Microsoft is too late to the game. It feels like they're too far behind in contrast to the competition. The software and W(P)8 platforms should've been released like a year ago...or more!

Finally a new player in the Dutch market (we only have Spotify and something called Deezer). I agree with your Justins Apple hope, but not only for Apple. I just hope that the music industry will be forced to accept lower margins, so that services like Xbox Music, Apple iStream (I like to call it that way) and Spotify can earn more and get cheaper.
