March Madness 2017 is a month-long competition on PopCrush to determine the best of the best of South Korean boy bands and girl groups.

UPDATE: This round is now over. Vote for SUPER JUNIOR in the final round!

Phew! Y'all are not playing around. After well over 15 million votes (!), the first round of PopCrush's 2017 March Madness series comes to a close today (Mar. 10). And the winners of that first round? SUPER JUNIOR, edging out NCT 127 with a whopping 83%, moving forward with 127,000 votes. Meanwhile, with 50.34% of votes, BTS also moves into the semi-finals, successfully defeating B.A.P.'s 49.66% in a close call after nearly 2 million total votes. Excellent job all around!

But the battle is only heating up: it's time for the semi-finals!

SUPER JUNIOR, which first debuted well over a decade ago, recently revealed that they're working on a new album, and are planning to make a major comeback at the end of 2017. Their last effort, Devil, was released in 2015 — so it's more than time for their return.

Following the release of their Wings repackage You Never Walk Alone in early February, the Gaon Award-winning Bangtan Boys are flying high with YouTube record-breaking music videos for cuts like "Not Today" and "Spring Day." They're also about to head out on a global tour in 2017, including stops in North America.

The battle starts now: place your vote between SUPER JUNIOR and BTS. This round ends on March 20.
