Groove Music Pass -- the Microsoft streaming music service formerly known as Zune Music and later Xbox Music before being rebranded to "Groove Music" in 2015, is one of Microsoft's few purely consumer-focused cloud services.
Microsoft will continue to run Groove Music Pass until the end of calendar 2017. After that point, those users with any remaining months of paid subscription to the service will be reimbursed. Starting this week, Microsoft will be encouraging those using Groove Music to migrate their playlists and music to Spotify.
Microsoft will continue to update the Groove Music application on all Windows devices, however, allowing those who have music stored in OneDrive to continue to play and manage their music through that app. But after December 31, 2017, the Groove Music app will no longer allow users to stream, purchase or download music.
