YouTubes New Feature: Just hum a song and find it in seconds

YouTube is testing a new feature that lets users identify songs by humming, singing, or recording. The feature is currently available to a limited number of Android users, but it has the potential to be a valuable tool for song discovery. If you've ever had a song stuck in your head but couldn't remember the name, this feature could be for you. Just hum the melody and YouTube will do the rest.
