alphadogg writes: It's one of those "You mean it was still alive?" moments: Microsoft today officially has killed off its Zune music streaming and download service. The company notified users in September that Zune services would be retired on Nov. 15. Microsoft has been phasing out its Zune brand for some time now, with Zune music service being morphed into Xbox music and then Groove music. Devices were discontinued in 2011.
