Apple announced iTunes Radio, the company’s long-rumored streaming music service. iTunes Radio is a free, ad-supported service, and it’s ad-free for iTunes Match users. The Pandora-esque service lets users choose featured music stations, or create their own stations based on specific artists. iTunes Radio keeps track of played songs within its history. Initially launching in the U.S., iTunes Radio is built into the iOS 7 Music app, and it will also be built into iTunes for Mac, PC, and Apple TV.
