Identify songs and TV shows quickly by holding up your device to the audio source and tapping a button on the Shazam app. From there, you can navigate to the song or video on YouTube or a 30-second iTunes preview or in Rdio. If you upgrade Shazam for $6.99, you'll enjoy an ad-free experience that lets you jump into full songs on Spotify or Pandora.
The newly-added Auto Shazam recognizes songs and TV even while your phone is locked. Plus, the app now allows you to share Shazam tags (your discovered songs) via WhatsApp, Pinterest and as iMessages on iPhone.
