Hey, iOS 7 wasn't the only thing to get a debut yesterday: Apple's iTunes Radio was officially launched along with iOS 7, ushering in a new competitor to go along with Spotify and Pandora for your radio needs. 

Yet, what seperates iTunes Radio from these other services, at least as of now, is that users can choose themed stations put together by artists and companies. Starting yesterday, stations curated by guest DJs Kary Perry and 30 Seconds to Mars frontman Jared Leto were up, along with stations offered by Twitter and Pepsi. Twitter #music station will play songs that are trending on Twitter, and Pepsi's four stations will play trending music and pop songs, along with country, latin and, you guessed it, EDM. It's a nice touch to the whole digital radio scene, since many services offer music based on algorithms, which—though they work well—aren't entirely spot on ("Rockin' Robin'" on Nine Inch Nails radio, Pandora?) 

iTunes Radio is free, and will be ad-based for those who don't have iTunes Match, which costs $24.99 a year. Those of us who don't have iTunes Match will be seeing ads from McDonald's, Nissan, Pepsi and Procter & Gamble—because when you think of cool, you of course think Procter & Gamble.
