After a long year away, SNSD is finally back with a new song called "The Boys" and they've brought a fierce new image with them! The girls dished out a confident swagger in their performance that drew full-out screams from the audience. Their stage on 'M Countdown' today wowed the audience with its dramatic setup, which perfectly reflected the concept of "The Boys". In an earlier interview, Sooyoung explained the key point in their choreography, saying,"We tried hard to make [the dance] match the song, however, it's not as aggressive or powerful as we thought initially. The 'going down' movement during the rap portion came about because there needed to be an impact at that point. The choreography team was trying to decide whether or not to include that move, but we insisted that we'd do it. They asked if it would be okay to just have 4 of the members do it, but all the members stated that they wanted to do it." Looks like the girls managed to bring down the house with them.
