Congrats to users Allaman3, gardenmama, and jodyann07 whose prediction brackets came in first, second, and third respectively.
Thanks to everyone who voted. The next big question, of course, is which version of "Silent Night" do you love the most? Be sure to tell us about it in the comments.
UPDATE December 22: Final four ends and final matchup begins
The final four saw powerhouse songs get knocked out. "Silent Night" knocked out the classic ballad "White Christmas" and "Rudolph The Red-Nosed Reindeer" bested Elvis Presley's "Blue Christmas."
UPDATE December 20: Round 4 Voting in Christmas Song Madness ends
Round 4 saw "Silent Night" knock out "O Holy Night" and "Rudolph the Red-Nosed Reindeer" push "Let It Snow" out of contention, but it was "White Christmas" that saw the biggest win, besting "I'll Be Home For Christmas" with more than two-thirds of the vote. But that win won't be a shock for anyone who knows that Bing Crosby's "White Christmas" holds the title of best selling single record of all-time, according to Guinness World Records.
The tightest race came between anther Crosby hit, his "Little Drummer Boy/Peace On Earth" duet with David Bowie. That tune held a solid 14-point lead for most of round 4, but Elvis Presley's fans came out in full force in the final hours, and "Blue Christmas" ultimately overcame to win by a tiny 2 percent margin.
UPDATE December 18: Round 3 Voting in Christmas Song Madness ends
As three rounds of Christmas Song Madness ended we said goodbye to hits like "Joy To The World," "O, Come All Ye Faithful," and "All I Want For Christmas Is You."
"Frosty the Snowman" lost in the tightest race of round 3, only 200 votes behind "Let It Snow," which advanced to our "Elite Eight" round to go head-to-head with "Rudolph The Red-Nosed Reindeer."
At this point in the tournament, we had some big names matching up, and the decisions were bound to get harder. Would the David Bowie and Bing Crosby version of "The Little Drummer Boy/Peace On Earth" beat Elvis Presley's classic "Blue Christmas"? And how will inspirational favorite "Silent Night" do when up against "O Holy Night"?
UPDATE December 16: Round 2 Voting in Christmas Song Madness ends
Round 2 saw Mariah Carey's 20-year-old modern classic "All I Want For Christmas Is You" get knocked off by Elvis Presley's version of "Blue Christmas" with Presley's 1957 hit knocking Carey's 1994 love song off 69.6 percent to 30.4 percent.
The tightest race of round 2 came between "Mary, Did You Know?" and "Feliz Navidad," with the former squeaking by the latter by fewer than 100 votes. The second closest race was won by "O, Come All Ye Faithful," which snagged 51.8 percent of the vote to knock out "The Little Drummer Boy." But at least one version of "The Little Drummer Boy" is still alive, as the David Bowie and Bing Crosby version of the song - mixed with "Peace On Earth" - managed to beat out the bluesy Christmas tune "Please Come Home For Christmas."
"Silent Night" continued its run as a fan favorite, moving onto round 3 with a 55-point win over "Angels We Have Heard On High," but the biggest blowout of round 2 went to "Rudolph the Red-Nosed Reindeer," which nabbed a massive 79-point margin of victory over "I Want a Hippopotamus for Christmas." Sorry, hippos. Better luck next time.
UPDATE December 13: Round 1 Voting in Christmas Song Madness ends
Mariah Carey's 20-year-old modern classic "All I Want For Christmas Is You" carried her to victory with 68.4 percent of the vote against Paul McCartney's 1979 "Wonderful Christmastime" in round 1. Mariah will have her work cut out for her in round two. She'll square off against Elvis Presley's 1957 version of "Blue Christmas," which easily dispatched John Lennon's 1971 "Happy Christmas (War is Over)" in a landslide, claiming nearly 80 percent of the vote in a round one match-up.
Other notable outcomes in the first round included "Jingle Bells" narrowly falling to "Winter Wonderland," 51.1 percent to 48.9 percent. In the tightest first-round match-up, "Santa Baby" barely edged "The Chipmunk Song," 50.6 percent to 49.4 percent. And in the first round's most lopsided contest, "Silent Night," a heavy favorite to go all the way, clobbered "Once In Royal David's City," 92.8 percent to 7.2 percent.
Whether you're hearing them at the mall or on the radio, the holiday season means Christmas songs are wafting through your ears and getting stuck in your heads. We're getting into the spirit this year by bringing a little springtime tradition to the Christmas season with a March Madness style competition that pits Christmas songs against each other -- and you'll get to the decide the winner.
We've amassed a list of 64 of the most popular and fun Christmas songs, and we're putting them all head-to-head, round-by-round until we finally crown America's Favorite Christmas Song. Vote for your favorite songs in the bracket below, then come back to keep voting each day. Along the way, you'll learn interesting trivia about all the songs in the tournament. (Check out some fascinating tidbits just below the bracket.)
Did you know the original lyrics to 'O Holy Night,' were penned by Placide Cappeau de Roquemaure at the behest of a parish priest of southern France in 1847? Cappeau, a well-known one-handed businessman and poet, was either an 'avowed atheist' or a rare churchgoer -- depending on which account you believe -- but he's generally believed to be a casual Christian at best. Meanwhile, the man he commissioned to write the music for the beloved Christian carol, Adolphe Charles Adams, was Jewish. (Look below the bracket for the rest of the story.)
When the church made this discovery, leaders weren't pleased. As Ace Collins explains in his book, 'Stories Behind the Best-Loved Songs of Christmas' eventually church leaders became so concerned about the "total absence of the spirit of religion" that they tried to ban the hymn, but the French people already loved it and wouldn't stop singing the song.
That's far from the only amazing fact about a Christmas carol. "White Christmas" is the best-selling single of all time, according to Guinness World Records. 'The Christmas Song' -- or 'Chestnuts Roasting On An Open Fire' as most probably remember it -- was purportedly written during a heat wave by a lyricist trying to conjure up thoughts of cooler weather.
Which tune will claim the championship title of Best Christmas Song? Only you and your fellow voters can decide, but the AOL editors went on the record with their predictions about which song will come out on top -- and we definitely don't all agree.
