This year, Google wants to be more involved in your Christmas, beyond just being a place where you can search for the perfect present — now, when Android users search “let’s go caroling” on Google, they’ll be treated with a surprise karaoke.

The festive “Easter egg” is a hidden feature that will pop up and provide a list of songs to choose from. The song will begin to play and everything you need to sing a Christmas carol is provided. The lyrics pop up on screen, complete with a bouncing red ball to keep you on track.

Since it’s exclusive to Android users, this hidden Google search feature is a fun way to reward its customers as well as show off something festive for the season that its search is capable of.
