When you can’t name that tune you hear at a restaurant or party, or just the earworm stuck in your head, let your phone do the work for you. You can even hum a few notes for an answer. 

• Let’s start by using Google. Open the Google app or search, tap the microphone icon, and ask, “What's this song?” or click the “Search a song” button. Then start humming for 10 to 15 seconds. It works very well. 
• For songs playing around you, on an iPhone, use Shazam. Open the Control Center and tap the Shazam button. Let Shazam listen for a few seconds, and you’ll get the song’s title. Shazam is also available as an app for Android. 
• For tunes playing in video games, TV shows and movies, go to Tunefind. It lists songs by episode, games, movies and television shows.
