The app is said to contain four tabs including one for "Suggested" tunes that the service things you might enjoy. The "#NowPlaying" tab plays songs being played by followers using the same hashtag while "Popular" plays songs that are trending. "Emerging" offers you songs and artists that are up and coming. Clips of music can be played inside the app thanks to third party music services like Soundcloud and iTunes while music videos can be viewed from Vevo which is a service formed by Universal Music and Sony.
In a timely announcement made earlier on Thursday, Twitter announced that last year it had purchased the music site We Are Hunted and used the acquired crew to help it build the new app.
