Girls' Generation dominated 2009 with their mega hits Gee and Genie and now they're setting off a whole new K-pop craze with their second full-length album Oh! Created by hit songwriter Kenzie, the title dance song is an electro-pop exclamation with sweet lyrics about confessing love. The girls present a variety of song styles in the 12-track album, which includes Boys & Girls featuring SHINee's Key as well as Gee and Genie.
