Today from South by Southwest, Rhapsody is making a catalog of music available for sharing on Twitter. With this launch, Rhapsody becomes the first streaming music service to offer licensed full-track playback to music fans on Twitter.

Using Twitter's audio card technology, Rhapsody members can now share songs with their followers directly from the Rhapsody app. While listening to music on Rhapsody, a member can tap the Twitter icon, add comments and hashtags, and share the full-length song. Friends and followers will see the Rhapsody audio card in their Twitter stream and can press the play button to hear the song that inspired the Tweet.

The launch of Rhapsody audio cards also makes it possible for any Twitter user to listen to entire songs without leaving the Twitter app. Once downloaded, Twitter music fans can explore the more than 34 million tracks in the Rhapsody catalog through a preview of the service. This offer is initially available in the U.S.
