Merry almost Christmas! Today, PopCrush is celebrating the holiday season with a new set of Christmas-themed Sound Off tunes. Justin Bieber has just released his LP 'Under the Mistletoe,' and his lead single off of the album, 'Mistletoe,' has become a new holiday favorite among fans.

Kelly Clarkson is also getting into the holiday spirit with the release of her new wintery single, 'I'll Be Home for Christmas.' Unlike Bieber's smooth guitar-strumming, finger-snapping 'Mistletoe,' Clarkson's Christmas song is a slow piano-driven track that shows off the singer's stunning vocals.

Rules of ‘Sound Off’:
There’s only one rule for our ‘Sound Off’ series: If a song remains the reigning champ for five straight days, it is retired to PopCrush’s ‘Sound Off’ Hall of Fame. With tons of great tracks coming out everyday day, we have to give other artists a chance to win!
