On the heels of its Spotify app release on Friday, Twitter's #Music platform is taking a swing at Rdio's streaming music service as well. Friday night, Twitter announced a new page within Rdio that would display 15 different #Music-generated playlists, including trending song and artist charts. The playlists are continuously updating, but otherwise fairly meager compared to the more polished Spotify app. Still, the possibility of playlist porting shows #Music's algorithms to be surprisingly versatile. Unlike Rdio's Heavy Rotation service, #Music playlists will import listening data from outside the app, potentially a boon for a smaller service like Rdio.
