It's almost time to say some tear-filled goodbyes to 20 incredible videos competing in Round 1 of Fuse's Top 40 of 2014 competition. This means your votes are more important now than ever. And tomorrow is the last day to put up the good fight for your fave artists from the first round!

Round 1 has proven to be quite the nail-biter. While certain vids almost immediately emerged as frontrunners in their head-to-head matchups, others are down to the wire—and they need your help!

The Ariana Grande vs. Meghan Trainor matchup as well as A Great Big World/Christina Aguilera vs. Sia battle have been neck and neck since we kicked off the round. 

It's also a tight battle of the bands with American Authors vs. Bastille. Plus, the star-studded matchup between Beyonce/Jay Z's "Drunk in Love" and Eminem/Rihanna's "The Monster" is getting closer everyday. 

Your votes can flip the scores—and change the final Round 1 winners—if you rally now!

And don't forget about Wild Cards! Even if your artist doesn't win outright, four eliminated artists with the highest number of votes from this round will be thrown back into the ring for Round 3. So your continued votes are crucial! (Curious about exactly how the Wildcards work in Top 40? Here's a quick explanation.)
