Fuse's Top 40 of 2013 is coming down to the wire, with only eight artists remaining. Let's take a look at the match-ups:
Demi Lovato vs. Britney Spears: Demi's "Heart Attack" video is facing off against Brit's "Work Bitch" with Britney currently taking a slight lead.
Imagine Dragons vs. Katy Perry: The Las Vegas rockers' summer smash "Radioactive" is duking it out with Katy's infectious hit "Roar," and "Roar" is dominating by almost 20 percent.
Eminem vs. Chris Brown: The rapper's manic video for "Berzerk" and the R&B singer's "Fine China" are fighting mano-a-mano, and Em is pulling out ahead.
Rihanna vs. Kendrick Lamar: Will RiRi's "Stay" win out over K. Dot's "Bitch, Don't Kill My Vibe"? Right now it's looking that way.
Only four of these artists will make it to the coveted Final Four and move on in the hopes of taking home the Top Video of 2013. Who will it be? You decide—cast your vote for the Top 40 of 2013 right now. Round 4 ends this Wednesday night at 6PM ET.
