Janet Jackson, ‘Rhythm Nation’ vs. A-Ha, ‘Take On Me’ — Greatest Pop Video of the Modern Era [Semi Finals]

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

Long before Beyonce and trench coat-sporting backup dancers moved through "Ring The Alarm" like a seasoned drill team, Janet Jackson, in stunning black-and-white fashion, set the standard for militaristic movement in music videos. In "Rhythm Nation," Jackson executed isolated movements as if her life and the life of her fellow performers depended on it, proving impact could come without gimmicky effects or a bevvy of cameos.

The 1989 tune is already cruising through our tournament...does it have the right moves to reach the 1980s bracket's final round?

Or, will Norway's A-Ha take one step closer to the ultimate Greatest Pop Video battleground? Almost equally as averse to color, the video finds a young woman tucked inside a comfortable diner's booth flipping through a black-and-white comic book. Soon, the images inside come to life, and though she's hesitant, she decides to dive into the published world, abandoning her check and cup of coffee. Imaginative and upbeat, the video set the standard for daydreamy and otherwordly treatments to come, but does it have enough momentum to remain in print?

This round will end on November 20 at 5 PM ET. Vote now!
