If there’s a melody rattling around in your head for which you just can’t quite put your finger on the title, you may be interested in testing out this new YouTube feature.

This feature is still in a test phase on YouTube. The video streaming platform has developed a new option for users on the Android version of the app, enabling them to find the title of a song simply by humming a melody, singing it, or playing an excerpt of a recorded piece of music, as with the Shazam app.
