HAM welcomed the new year with the release of second hit track Doogeun Doogeun a few weeks ago; the girls got to perform this song on the January 29 episode of Music Bank. This song strays from the concept that kpop followers got used to with T.T Dance, revealing a sweet tone and new side to the girls. Check out this evening's performance of Doogeun Doogeun: http://www.youtube.com/watch?v=D_fMGWQf5iI
