Missed this yesterday. Kind of makes me feel uneasy, in that it'll probably mean Spotify going down the toilet (or bought out by MS to actively flush it). Thoughts? Is this the streaming service we've been waiting for or just one me-too too far?
Depends on the quality as well. The thing that impressed me with Spotify is the excellent quality even on the lower bitrate offered with the free service. You'd assume the Microsoft version would be WMA files which I think will be worse unless a substantially higher bitrate than the Ogg Vorbis used by Spotiufy.
