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. And to kick off the competition, why not start with a classic pop "rivalry" from all the way back (to the future) in the 1980s?

Madonna's "Like A Prayer" music video is, genuinely, iconic — and just one of the many instances in which the Queen of Pop majorly ruffled feathers and broke barriers as a pop star with controversy: The religious-themed, Mary Lambert-directed video features a slew of then-shocking imagery, including stigmata, burning crosses and murder, tackling themes of racism and bigotry as Madonna witnesses a black man wrongly accused of a white woman's murder. The clip was condemned by The Vatican, banned, and even caused Pepsi to pull out their sponsorship deal. Years later, it's still considered one of Madge's most important and instantly memorable works.

Cyndi Lauper's "Girls Just Want To Have Fun," on the other end of the spectrum, is about exactly that: Fun. The rowdy, girlfriend-filled clip sees the singer in full-on '80s rebel teen mode. But make no mistake: The clip wasn't all just rebellion in the name of fun — it doubled as a supreme feminist statement. (It should be worth noting that the song also came in second place to Michael Jackson's "Billie Jean" in our song competition!)

And now, it's time to decide: Which video ultimately moves forward in our competition?
