Xbox Music is now Groove. This is news that Microsoft detailed weeks ago, but it's only now—coinciding with the release of Windows 10—that we're seeing the name change on Android.
In the latest version, the rebranding has taken place. Microsoft highlights the ability to upload your music to OneDrive, stream music with a Music Pass subscription ($9.99 a month or $99 a year), and save files for offline use.
Not wasting any time, Sonos has already announced that it supports Groove. The integration is still in beta, but you're free to try it out right away. Look for it under Add Music Services.
You can find the Play Store link in the widget below. Alternatively, you can download the app directly from APK Mirror.
