Facebook announced last week an expanded partnership with streaming music service Spotify that would bring a new way to listen to music or podcasts directly within Facebook’s app, which it called Project Boombox. Today, the companies are rolling out this integration via a new “miniplayer” experience that will allow Facebook users to stream from Spotify through the Facebook app on iOS or Android. The feature will be available to both free Spotify users and Premium subscribers.

The miniplayer itself is an extension of the social sharing option already supported within Spotify’s app. Now, when Spotify users are listening to content they want to share to Facebook, they’ll be able to tap the existing “Share” menu (the three dot-menu at the upper right of the screen) and then tap either “Facebook” or “Facebook News Feed.”
