Apple announced iTunes Radio today, a new feature that is built into the Music app in iOS 7. The new feature offers music discovery through featured and genre stations provided by Apple or through the creation of new stations based on a specific artist or song. iTunes Radio keeps track of all of the songs listened to for easy access later for purchasing or repeat listening. iTunes Radio will also be available on Mac and PC through iTunes and Apple TV. It will be free with ads while iTunes Match subscribers get an ad-free experience. The service will be available starting in the US only at first.
