I’m going to take a wild guess here and say that most people use Shazam just to identify songs, and have no idea that the software has a lot more features basically hidden under the hood. That’s why Shazam will receive an update today that brings a new UI placing real-time lyrics from and center right next to the video for the song you just tagged. The new app also make it easier to buy and/or stream content. The update should be available in the App Store shortly…
