With Christmas just around the corner, Google has secretly updated Google Now with a neat little feature. It has added a new voice command that allows you to get into the holiday spirit by singing carols. All you have to do is open the Google Search app, tap the microphone, and say "let’s go carolling". If you own a Moto X, any newer Motorola Droid smartphone or a Nexus device, you can do the same thing directly from the homescreen.
Google Now allows you to sing along one of five available songs. Once you select the desire one, it plays the music and displays simple controls as well as karaoke-like lyrics. With such a helper in your pocket, you can attend the midnight mass and leave your song book at home.
