Back in March we reported that YouTube Music was testing a sound search feature that would let you to find music by humming, singing or playing it. It made its way to some users in May before Google appeared to roll it back – well, now it's finally rolling out for everybody on iOS and Android.
The feature's accuracy will of course depend on how well you can sing or hum it; while 'sound search' is clever, it isn't so smart that it can recognize a version that's not even in the same zip code as the original.
