It's time once again for our sexy spin on the NCAA's annual March Madness Tournament! This year, we'll be offering up the hottest guys in TV, movies, and music in a series of polls. In this round, it's up to you to decide which musician topped your hotness chart this year. From established names like Justin Timberlake and Drake to rising stars like Troye Sivan (not to mention two former One Direction dudes), we don't blame you for having a hard time choosing between these crooners. Click the arrows to vote your favorite guy to the top as many times as you want, and check back as we reveal the winner on April 2!
