Google is testing a new YouTube feature that lets you hum or record a song to search for it.

If you’re part of the YouTube experiment for the feature, you can hum or record three or more seconds of a song so that Google can try to identify it, according to a support page. Once YouTube identifies the song, it will show you relevant content about that song. Basically, it’s a Google-y take on Shazam, which is owned by Apple.

Not everyone will have access to the experiment at first, though. Google says it’s rolling out to “a small percentage of people across the globe who watch YouTube on Android devices.”

Google says it’s also testing a YouTube feature that bundles multiple uploads in “a short amount of time” from a single creator into a special “channel shelf” in your subscriptions feed. “We’re experimenting with this for a few reasons — as a way to make it easier for viewers to find the content they’re looking for, to put less pressure on creators to upload multiple times a day, and to make it simpler for viewers to engage with the content in the shelf and / or navigate to other content while scrolling in their feed,” Google says. The feature will be available first to a “small percentage” of people.
