M.I.B’s Kangnam released a chart-topping solo song only weeks before the group heads to New York City.

Kangnam, who became one of 2014’s breakout stars for his appearances on variety shows, released “What Do I Do?” on December 26. The same day that it was released “What Do I Do?” topped multiple Korean music charts. Kangnam’s popularity spike comes immediately before M.I.B heads to New York in order to appear at the 55th Annual Korean-American Day Celebration.

The images for the single "What Do I Do?" featured Kangnam in New York City.

“What Do I Do?” took the number one spot on Daum Music’s realtime chart, and also appeared on music charts from websites like Genie, Mnet, and Melon. Kangnam shared a tweet with a picture of the music charts when “What Do I Do?” reached number one.
