Microsoft Corporation is launching Xbox Music on web browsers today. Xbox Music Pass is now available on PCs, tablets, the Xbox 360, smartphones, and on the web. All of your playlists will automatically stay in sync. You can test out Xbox Music Pass for 30 days free. You can access the service at music.xbox.com. Microsoft Xbox Music launched back in October on the Xbox 360 game console, Windows Phone 8, and the Windows 8 operating system. Some of the expected upcoming features of Xbox Music includes cloud storage for music that is not in the Xbox Music catalog and social features that lets you share music with friends and family.
