When performing a Google search for “Let’s go caroling” on an Android or iOS device, the first result includes the question “Which carol would you like to sing?” along with a list of the following five carols:
- “Jingle Bells”
- “Up on the Rooftop”
- “Deck the Halls”
- “O Christmas Tree”
- “We Wish You a Merry Christmas.”
Selecting one of the carols delivers a karaoke-style music player. The song’s music plays while lyrics are displayed below the control buttons, helping carolers keep time with the tune without having to hum any forgotten words.
