If you haven't used the handy little app Shazam, give it a try. It's an easy way to figure out that song playing on the radio, especially if you don't have a fancy screen in your car that tells you. Apple said they are buying Shazam - and they could be planning to use it with Apple Music. Shazam has seen decreasing downloads recently - which may have prompted the sale. "Waning use of Shazam reflects increased integration onto the iPhone. Shazam is now accessible from Siri, the iPhone personal digital assistant, allowing users of the iPhone to identify songs without having to open the Shazam app."
