Earlier this week, Microsoft announced that it was discontinuing Music Pass support in Groove, inviting subscribers to move over their music collection to Spotify. Fast Ring Insiders can now download the version 10.17083.1815.0 of the Windows 10 Groove app, which enables a new integration with the Spotify Windows Store app.
After installing the update, you’ll notice a new Spotify button below the Settings cog, which when clicked launches the Spotify Windows Store app (or redirects you to the Windows Store listing if you have yet to install it). To transfer your music collection to Spotify, you’ll have to go into settings and click the “Move over your collection to Spotify” button. You will then see a pop-up window with instructions on how to login or create a Spotify account.
After signing into your Spotify account, the transfer will begin and the whole process will take a few minutes, depending on the size of your music collection. All songs from your Groove Music collection, including playlists and music stored on OneDrive will be added to your Spotify music library (assuming Spotify already has licenses for all of your songs). Be aware though that Spotify currently limits your music library to 10,000 songs, so you may not be able to transfer all your music collection if it’s bigger than that.
As a reminder, Spotify has a free tier with ads, and you can also use the app to listen to local tracks. While the Windows Store version is not a native UWP app, it's a solid desktop app that also supports Windows 10's native media APIs. Spotify also recently launched on the Xbox One, but the Windows Phone app is now unfortunately in "maintenance mode."
