Microsoft has announced that it's saying goodbye to its Groove Music services after December 31st, 2017. Unlike in the past, there isn't another Microsoft-branded service waiting in the wings. Instead, the company is transitioning everyone over to Spotify. The Groove Music app will offer to migrate your collection and playlists through an update, starting with a preview version this week and more broadly on October 9th. Groove Music Pass subscribers will have the option of migrating to Spotify until January 31st. And if you paid for Music Pass beyond December, you'll get a refund for the amount of time you didn't get to play. Thoughts ?
