Okay, it's getting serious.

When we launched the Battle Of The Bands, we knew that the competition would be fierce. We didn't know how fierce — but over 200,000 votes later, we now know that y'all are not playing around.

And so, we're up to the semi-finals.

In one corner, we've got "Come Back Home" superstars 2NE1, the massively popular K-Pop quartet who just bested Girls' Generation in our first round, narrowly edging out the equally giant crew with 50.78% of the vote.

And in the other? Why, the stateside, X Factor USA-bred ladies of Fifth Harmony, who proved they were #WorthIt after snagging a victory away from Little Mix in Round One with 52.24% of the vote.

It's time now for the two fabulously talented troupes to face off in our semi-finals. Who will come out on top?

You have until October 26 at 5 PM ET to vote. The competition is now open. Go, go, go!

UPDATE: This poll has now ended. Congratulations, 2NE1! Now head on over to vote in the final round: One Direction vs. 2NE1.
