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!

We're back with the semi-finals of the 2010s, and the competition is seriously getting fierce. Last week, two vocal dynamos — Sia and Adele — went head-to-head in the first round, where Adele successfully fought her way through, swinging over Sia's "Chandelier" with 54.1% of the vote. The 25 superstar is busy breaking records left and right with her new LP, but will the clip for her powerful 21 anthem "Rolling In The Deep" be enough to take down two divas at once?

Meanwhile, Gaga and Honey Bee made a great escape in their own first round, narrowly crushing Katy Perry and her whipped cream teenage dreams with an insanely small margin — 50.2% of the vote to be exact. But will their mad jailbreak masterpiece be enough to throw Adele off her singin' chair?

It's time for you to decide: Between Adele's "Rolling In The Deep" and Lady Gaga and Beyoncé's "Telephone," who had the more iconic video of the '10s? Place your vote below. This round will end on December 10 at 5 PM ET.

And while you're at it, be sure to vote in the other rounds...
