Today, Microsoft announced a bad news for fans of Groove Music: The company is ending the Groove Music Pass subscription and is offering a seamless transition to Spotify. Furthermore, customers won’t be able to buy music from the Microsoft/Windows Store anymore. Movies, TV and eBooks will still be sold.
Starting this week, Windows Insiders with a Groove Music Pass subscription will be able to move content to Spotify via a Groove Music App Update. Non-Insiders will get this possibility next week. On December 31, 2017, Groove Music Pass will be closed down completely.
The Groove Music app in Windows 10 itself will be continued. Nevertheless, you will only be able to play music from your PC or from OneDrive.
I am pretty sure that Groove Music is not the last service Microsoft is killing. It would be really surprising if Microsoft is continuing to support its Movies & TV service.
