Congratulations to Kelly Clarkson on beating out Justin Bieber in yesterday's Sound Off! The 'I'll Be Home for Christmas' songstress won the most fan votes for her beautiful holiday ballad, which means that she will take on a new challenger today. Today, Ms. Clarkson will take on the 'Glee' cast and their original Christmas tune 'Extraordinary Merry Christmas.'

While Clarkson produced a smooth and sultry Christmas tune with her powerful and longing rendition of 'I'll Be Home for Christmas,' staying true to the overall sound of the classic, the 'Glee' cast are taking things to a more bubbly, pop realm. Their feel-good 'Extraordinary Merry Christmas' song has Christmas bells, but also incorporates pounding drums and lighthearted guitars that are reminiscent of Katy Perry's 'Last Friday Night.'

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!
