Google has added a new feature that lets you figure out what song is stuck in your head by humming, whistling or singing – a much more useful version of the kind of song-matching audio feature that it and competitors like Apple’s Shazam have offered previously. As of today, users will be able to open either the latest version of the mobile Google app, or the Google Search widget, and then tap the microphone icon, and either verbally ask to search a song or hit the ‘Search a song button’ and start making noises.

The feature should be available to anyone using Google in English on iOS, or across over 20 languages already on Android, and the company says it will be growing that user group to more languages on both platforms in the future. Unsurprisingly, it’s powered behind the scenes by machine learning algorithms developed by the company.
