MTV has launched MTV Artists for iPhone, an app that can help you identify songs and connect you to artists. The Shazam-like song ID listens to music in order to identify it, though you can also search lyrics to find the song you're looking for. You can also find artists on Facebook and Twitter, buy music from iTunes, find tour dates and buy concert tickets. Explore a wide variety of content, including music videos and free streaming of MTV-selected tracks. MTV Artists is a free download for the iPhone, and can be found on the App Store now.
