twitter-music-app_web.jpgLOS ANGELES — Twitter has launched a service that lets people find music they like and tweet songs from iTunes, Spotify and Rdio. Twitter made the app available for download from Apple’s online store and also launched a Web version on Thursday. Twitter said the service will eventually be available on Android devices as well.

The service uses information from Twitter chatter to detect popular tracks as well as new artists. Users who follow musicians can see other artists those musicians follow and can listen to 30-second clips of songs by them.

Tapping the play button on an image of an artist plays a clip from one song picked to represent them. Users can tap another button that opens iTunes where they can buy the track. Or they can play full songs by signing up for a $10-a-month subscription from Spotify or Rdio.

While users can tweet what they’re listening to and add a few characters of comment, they have to go back to the regular Twitter app for normal Twitter functions. However, the people you’re following and who’s following you are integrated across both apps.

The music app is strikingly more visually appealing than the regular Twitter app. Squares of photos of artists fill the screen and bounce around in response to swipes. The app also starts a turntable spinning with a little picture of an album cover art when playing a song. In a blog post, the company said its service “will change the way people find music.”
