Election Day is tomorrow, but there's another important vote you need to cast first—and that's for the best music video of the year! But vote quick because Round 2 in Fuse's Top 40 of 2013 ends tomorrow!

At 6:00 P.M. EST Tuesday, the pool of 20 remaining artists will halved: 10 losers will exit, while the 10 victors will continue to the final round. (Don't fret too much if your fave is gone, there are Wildcards!) And it's not too late to ensure that your favorite artist continues on, as most battles are still down to the wire! Selena Gomez vs. Paramore is still too close to call, while the war of the Justins (Bieber vs. Timberlake) is neck in neck.

Can Britney Spears fans make a comeback over the Katy Kats? Is Demi Lovato going to win over fellow former Disney star Miley Cyrus? Your favorite artist needs you now more than ever!

Watch and read about all of the video contestants in Fuse's Top 40 of 2013, then vote (and vote again!) to decide who deserves the No. 1 spot.
