Welcome to March Music Madness! Here at PopCrush, we've selected 32 of the most iconic pop songs released from the '80s to today (divided into brackets by decade) -- and now it's your job to vote and decide which song will be named the Greatest Pop Song of the Modern Era. May the best song win!

In this pop star face-off, we're pitting crooner Bruno Mars against the smooth-singing Robin Thicke. Bruno cemented his place in pop music history with his Grammy Award-winning 'Just the Way You Are,' while Robin's unforgettable 'Blurred Lines' was undoubtedly the feel-good song of the summer in 2013. Which song is better deserving of the title of Greatest Pop Song of the Modern Era?

Bruno Mars introduced himself to the world with his sweet ode 'Just the Way You Are' in 2010. Not only did the song leave girls everywhere swooning, the No. 1 hit (and Grammy Award winner) was empowering to women everywhere, with the sexy singer praising women's natural beauty with his sugary soprano voice.

Robin Thicke teamed up with Pharrell and T.I. to bring us 'Blurred Lines,' the controversial yet catchy tune with an equally provocative music video. Though the singer had long been an established artist, 'Blurred Lines' launched him into superstardom, earned him two Grammy nominations, and his raunchy VMAs performance with Miley Cyrus only furthered the song's popularity.

Which song is more iconic and meant to be the Greatest Pop Song of the Modern Era? You can vote once an hour until the polls close on March 11 at 12PM ET. The winning song will move on to the next round!
