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.

This round is now over! Vote for BTS in the semi-finals here!

The battle begins today between BTS and B.A.P, two of the newer, most popular acts on the K-pop scene now going head-to-head in the first round of PopCrush's 2017 March Madness series.

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.

B.A.P, on the other hand, are just getting started: the boy band returns with a new single album in March called Rose, with teasers dropping left and right. Their last full album, Noir, dropped last November, so anticipation is at an all-time high for B.A.P's return. They'll also be heading around six cities in the U.S. for their Party Baby Tour beginning in April.

The battle starts now: place your vote between BTS and B.A.P. This round ends on March 10.
