Microsoft have today launched their web based version of Xbox Music for Xbox Music Pass subscribers today, allowing them to stream their music library and favourite music directly from any browser. The web site is compatible with most modern web browsers, as expected, and will stream music from the service, much like Spotify.
Xbox Music on the web uses a UI very similar to its brother on Windows 8.1, the only differences being that you can't create or listen to Radio's on the website, however it's possible that Microsoft are working on implementing this feature.
You can check out Xbox Music at the source URL below, but do keep in mind that it requires an Xbox Music Pass. If you haven't tried Xbox Music Pass before, you will be offered a month free trial just by signing into your Xbox LIVE account. Go check it out now!
