PHILADELPHIA (CBS) - On today’s APP-tastic and Outta site – Shazam.

You might know Shazam as the app you use to identify that song on the radio, but the service has expanded to cover TV as well – and it’s doing so in a big way.

Just hold the app up and let it ‘listen’ to what you’re watching and you can get bonus content – from how-to videos to bonus behind-the-scenes features. Just keep an eye out for the app’s logo on screen as you watch.

Check out the Shazam app.
