Xbox Music is one of Microsoft`s best kept secrets - ubiquitous on Microsoft`s own consoles but poorly promoted, even on Microsoft Windows Phone devices. But on the eve of the iTunes Radio rollout, Redmond has woken up and remembered that it exists. The streaming service formerly known as Zune Pass has finally sprouted native apps for Apple iOS and Android devices, Microsoft has officially confirmed. A free web streaming "Pass" has also been launched at music.xbox.com capped to a limited number of hours.
