Hot 100 March Madness: The Winner Is...

After three weeks and hundreds of thousands of votes, we have a winner of the first-ever Hot 100 March Madness: Britney Spears' "Hold It Against Me"! The "Femme Fatale" single was voted the best song to hit No. 1 on the Hot 100 over the past two years, emerging from a field of 32 and winning all of its head-to-head matchups. When all was said and done, it was still Britney, b*tch.

The original bracket was comprised of the 32 most recent songs to top the Hot 100 chart. The match-ups within the bracket were determined by the dates in which each song topped the Hot 100: the most recent No. 1, fun.'s "We Are Young," is matched up against the 32nd most recent No. 1, Rihanna's "Rude Boy," and so on.

Looking back at the Final Four, over 80,000 votes helped push Britney and Katy past their equally formidable competitors. 53% of fans voted for "Hold It Against Me" over Adele's "Set Fire To The Rain," while 62% of fans picked "Teenage Dream" over Eminem's "Love The Way You Lie," featuring Rihanna.

The Finals were a different story: "Hold It Against Me" garnered 73% of fan votes compared to 27% for "Teenage Dream," earning the most lopsided victory of the entire competition. "HIAM" defeated Wiz Khalifa's "Black and Yellow," Rihanna's "Rude Boy," Bruno Mars' "Just The Way You Are," Adele's "Set Fire To The Rain" and "Teenage Dream" to win the Hot 100 March Madness crown.
