"Microsoft sweetened the deal for all its potential Windows 8 users a few days ago when it announced that adopters of the new OS would get an unlimited free Xbox Music Pass. This is a good way for Microsoft to promote both its new OS and, perhaps more importantly, its new music service. The new Xbox Music rises from the ashes of the old Zune offering but brings much more - and it's consistent across the entire Microsoft ecosystem.So if you're a Windows 8 user you might have noticed all of the updates for the first party apps that have been going on recently. One of them is for the Music app and if you haven't already updated you definitely should. Why? Well because this update brings the free music subscription that Microsoft mentioned a few days ago."
