YouTube Music will let you search by humming into your Android phone

The Android YouTube Music app is rolling out a feature that’s part Shazam and part your friend when you say, “hey what’s that song that goes...” right before you hum out a bar. The feature lets you hum, whistle, sing, or play a recording of a song to figure out what it is.

If you have the new feature, you’ll see a new waveform icon next to the microphone icon that appears when you tap the search button in the upper right corner of the app.
