Now Playing: Ever hear a song at the coffee shop and wonder who it's by? Now Playing uses on-device machine learning to figure out what the music is in your background, and it will display the artist and title on the lock screen (or in your notifications). It doesn't require an internet connection, so there's no data shared between you and Google. This isn't turned on by default, so head to Settings Sound and Vibration Now Playing and toggle it on. You can even turn on Now Playing History in case you forgot to write down an artist's name when you saw it earlier. Google added a button you can press in case Now Playing doesn't automatically identify a song, sorta like Shazam.
