They only had "One Shot," and they hit a bullseye!

In our K-pop K.O. competition, two K-pop songs battle for a week, with the number of fan shares determining the winner. K-pop's rising boy band B.A.P. took on and conquered Rainbow's "Tell Me Tell Me" with their hip-hop romper "One Shot."

We're already huge fans of the video (shot with a fat $900,000 budget!), so we're thrilled that the guys were able to dance their way into a big victory.

As for this week's battle...

VOTE for SHINee's "Dream Girl" OR TEEN POP's "I Wanna Love" in the K-pop K.O.!
