The Xbox Music service will be expanded to Windows-powered computers and tablets in due time, including the Windows 8 and Windows RT versions of the upcoming Surface tablet when October 26th rolls around to coincide with the Windows 8 operating system launch. Not only that, smartphones (definitely the ones running on Windows Phone 8) will also be getting the Xbox Music service as well. With Xbox users spending up to 60% of their time on entertainment services on the Xbox 360 console, Microsoft figured out that this is a good time to enter the fray with Xbox Music, which will continue where the ill-fated Zune service failed to take off. Microsoft will make Xbox Music available in 22 countries first, and hopes to deliver the service to iOS and Android-powered devices from 2013 onwards. [Press Release]
