Let the madness begin!

MTV's Musical March Madness is officially under way with voting in the first round of our bracket-style competition now open. Thirty-two of the biggest artists in music will be battling it out for the title in the sixth year of our tournament.

This year, with our new criteria in mind, we asked you to pick who makes the cut for the field of 32 contenders. We've gotten tons of submissions, including artists from a variety of genres. Pop divas will face off against rock stars, while boy bands will take on hip-hop artists, so it's truly anyone's game.

Veteran MMM participants like former champ Ed Sheeran, two-time winners Tokio Hotel, Paramore and Thirty Seconds to Mars, are all making their return to the bracket. Meanwhile, rookies One Direction, Demi Lovato, Rihanna and Wiz Khalifa make their big debuts. Check out the bracket to see the full list, along with the matchups, which were completely decided at random.

The first round of voting is open until Thursday, March 19, when the 32 contenders will be narrowed down to 16. You can help by voting for your favorite as many times as you wish and be sure to spread the word on Twitter, Instagram, Vine and Tumblr using the hashtag #MMM.
