The apps offer ad-free music streaming for subscribers, the ability to add songs, albums and playlists to your Xbox Music collection, playlist syncing with other devices and artist-based radio-stations.
One thing the apps don’t offer is offline listening, a functionality that Microsoft claims is coming “soon”.
Additionally, web-based music streaming on Xbox Music, previously available only to subscribers, is now open for everyone. The service will stay free (and ad-supported) for 6 months, after which the hours of free streaming will become limited unless you pay the $9.99 monthly fee (or $99.99 per year).
A Microsoft representative told us that new features, such as Radio for the Web and Web Playlist, are coming soon.
With these latest additions, Xbox Music is becoming a serious competitor to services such as Spotify, though Microsoft’s offering is still lacking in the area of social sharing.
