The free Internet radio service features over 200 stations "and an incredible catalog of music from the iTunes Store," Apple said in a statement as it opened its annual developers conference in San Francisco.
The ad-supported free music service is set to launch later this year and "offers music fans access to thousands of new songs every week, as well as serving up exclusive music from new and popular artists before you hear them anywhere else," an Apple statement said.
"iTunes Radio is an incredible way to listen to personalised radio stations which have been created just for you," said Eddy Cue, Apple's senior vice president of Internet software and services.
"It's the music you love most and the music you're going to love, and you can easily buy it from the iTunes Store with just one click.
