Microsoft has announced (non-Javascript version) (emphasis in original) that
As of November 15, 2015, Zune services will be retired. You will no longer be able to stream or download content to your device from the Zune music service. However, Zune devices will still function as music players and any MP3 content that you own on the Zune device will remain there. You'll also be able to transfer music to and from your Zune player.
Note Content that was purchased with DRM may not play if the license can't be renewed.
Existing Zune Music Pass subscriptions will be converted to Groove Music Pass subscriptions.
