After releasing their second album Oh!, SNSD kicked off their comeback with a tremendous start, hitting the 30k mark in album sales in one day. Many fans are guessing that SNSD's title track Oh! will be a huge hit as it took the # 1 spot in music charts faster than their previous hit track, Tell Me Your Wish (Genie). In the past week, the girls of SNSD have been teasing us a couple of times with their choreography of Oh!, until they released the MV on the 26th. Today, SNSD finally performed their comeback stage on Music Core, performing Show! Show! Show! and Oh!. With the outstanding choreography, their performance was absolutely terrific! Without further ado, check it out below! http://www.youtube.com/watch?v=DxBQTx7nGLw SNSD's album has already been released, but fans still have more to anticipate with SNSD's follow-up MV with a dark and sexy concept coming soon!
