Apple announced the Fall launch of iTunes Radio, a Pandora-like streaming service geared towards music discovery and driving increased iTunes sales. Available on iPhone, iPad, iPod Touch, Mac, PC, and Apple TV the service will be free and ad supported, or completely ad-free with an iTunes Match account. While it’s hard to call the offering a game changer, there are differentiating features like voice command integration with SIRI to make song requests. Apple’s biggest advantage though should be its ability to get exclusive tracks or album previews from big artists before you can hear them anywhere else.
