Google Search helps you find that earworm by humming

Sometimes when you're trying to look for a song, you can only remember the melody or the cords. Google wants to help you find the track you're looking for with a new feature coming to Search. It will let you hum, whistle, or sing a melody to identify the song for you. All you have to do is tap the mic icon on the Google Search widget or head to the Google app and ask, "What's this song?" or click the "Search a song" button.
The feature is available in English on iOS and in over 20 languages on Android, with plans to add more languages in the future.
