Shazam has updated its iPhone app to tag songs, TV shows and more on its own, no longer requiring users to open the app and tap a button whenever they want to tag something.

The feature, called Auto Shazam, comes turned off by default, but users can turn it on by switching a toggle once they've downloaded the latest update for the app. Once turned on, Auto Shazam will remain on in the background and listen for audio that it can tag while users go about their day doing other things.

The Shazam iPhone app has been updated to include Auto Shazam, a feature users turn on so the app will keep tagging audio in the background.

Any time the app tags a song or show with Auto Shazam, it will send users a notification with the name of the audio that it has tagged.

"Shazam is already known as fast and easy, but we want to become effortless," Shazam chief product officer Daniel Danker said. "The only thing easier than pressing a button is not having to press one at all."
