From Bruce Houghton at Hypebot:
After several days of celebrity only access, this morning Twitter opened its new web and iPhone app based music service to the general public. Twitter #music uses Twitter activity, including Tweets and engagement, to detect the most popular tracks and emerging artists. Songs on Twitter #music pull from three sources: iTunes for 30 second previews and if you’re a premium subscriber, full tracks from Spotify or Rdio.
Providing an effectiive way for artists to share with fans, #Music also highlights artists’ music-related Twitter activity: go to their profiles to see which artists they follow and listen to songs by those artists. Users can tweet songs right from the app.
For example, Oif you want to listen to music from the artists Wiz Khalifa follows, you can search for his name using the search icon in the top right corner. Then tap one of the artists you’re interested in and hit the play button to begin listening, or press play on the player to listen to all the artists.
Users interested in the songs that have been tweeted by the artists and people they follow on Twitter, can navigate to #NowPlaying.
And users discover new songs, they can tap the spinning disc in the lower left corner. This opens the player, from which they can tweet the track.
