In addition to announcing that the service is now up to 15 million active users and 4 million paying subscribers worldwide, Spotify also announced today that it is rolling out the radio streaming feature (previously only available on iOS) to Android. Same as the iPhone version, the feature provides ad-free radio streams for premium subs and ad-supported streams for free accounts. Unfortunately, the free streams are U.S. only at the moment. You can also save songs from radio streams to a “Liked from Radio” playlist.

What’s in this version:

There’s a great new radio experience in Spotify. Now you can discover and save music on the go! If your station plays a song you really like, save it with a single tap. New: Start a radio station based on your favorite playlist, genre, album, artist or song. New: Personalize your radio stations by voting songs up or down.
