Cast your vote for your favorite Top 5 single from the past year.

Billboard.com Hot 100 March Madness is back! The annual twist on the college basketball tournament bracket is now in its third year, and once again, we're asking pop fans to vote for their favorite recent hits on Billboard's Hot 100 chart.

Over the past two years, hundreds of thousands of votes were cast in our Hot 100 March Madness polls, and Britney Spears' "Hold It Against Me" and Britney Spears & Will.i.am's "Scream and Shout" emerged victorious in 2012 and 2013, respectively. Now, a new pop smash must be crowned, from a fresh field of 32 songs. Which song will win Hot 100 March Madness 2014?

Check Out The Current Hot 100 Chart

Like last year's Hot 100 March Madness tournament, we've gathered the 32 most recent singles to reach the Top 5 of Billboard's Hot 100 chart, and placed them in head-to-head match-ups. Over the next month, it'll be up to the fan votes in the bracket-style tournament to determine which song is the absolutely standout of these 32 hits!

Check out the full Hot 100 March Madness bracket below, and then support your individual favorites in the first round of voting.

From May 4, 2013 to the present chart, there have been 32 songs that appeared in the Top 5 of the Hot 100. The match-ups within the bracket were decided arbitrarily, so don't worry about NCAA-style rankings -- any of the 32 songs above has a great chance of following "Hold It Against Me" and "Scream and Shout," and tasting Hot 100 March Madness glory.

With no Britney Spears song involved in this year's tournament, several pop superstars have a real chance at earning their first Hot 100 March Madness victory… if they can overcome tough first-round match-ups. Can Lady Gaga's "ARTPOP" hit "Applause" take down Katy Perry's latest No. 1 single, "Dark Horse," in Round 1? Will Miley Cyrus' "We Can't Stop" effectively stop Imagine Dragons' "Radioactive" from rocking into the Sweet Sixteen? Lorde's "Royals" was a No. 1 hit for nine weeks, but can the song live the fantasy of March Madness victory by toppling "All of Me," the biggest hit of John Legend's career? And can Drake get some Grammy revenge on Macklemore & Ryan Lewis by striking down "Thrift Shop" with "Hold On, We're Going Home"? It's completely up to you to decide.

Next Monday (Mar. 10), we'll reveal the 16 songs that won their match-ups and survived the round of 32, and another round of voting will begin. On Thursday, Mar. 27, a new Hot 100 March Madness champion -- the Top 5 hit that you think was the No. 1 single of the past year -- will be crowned. Vote now in the match-ups below, and let the Madness begin!
