Last year, we ran a super-sized competition to determine the greatest pop song in modern history, from the ’80s to today. Now, we’re back — and this time, it’s all about honoring the best and boldest in music videos.

It's typical for pop videos to introduce new dance moves or usher in cutting-edge fashion, but when one can successfully implant language that's still commonly used seven years after the fact—that's lasting power. "If you like it then you shoulda put a ring on it," has been used in earnest and for fun since 2008, and the black-and-white, single-take dance routine that served as visual backdrop is classically iconic. Plus, lest we forget, Beyonce's video is the lone catalyst to Kanye West's infamous 2009 takedown of Taylor Swift at the MTV Video Music Awards. He wasn't necessarily wrong, though: "Single Ladies" may, in fact, be one of the best videos of all time.

Sometimes, less is more—not so for Lady Gaga, whose 2009 The Fame Monster video registered like a narcotics-fueled fever dream. "Paparazzi" was early proof that Gaga had a taste for the artistically bizarre, but "Bad Romance" kicked it up a notch. Featuring a burning bed, series of futuristic bathhouse pods and heels that would leave even seasoned models victims of the runway, the work is instantly recognizable to any casual pop consumer. Oh, and the song's still one of her best.

Both videos stunned with their imagery, but who do you want to see more of? You can vote once per hour until November 27 at 5 PM ET!
