Today, the nine cheerleaders of SNSD are back on Music Core! As SNSD prepares for their upcoming 'Black Soshi' comeback on March 18th, this will be their last performance of Oh! Fortunately, we don't have to worry about anything because SNSD will be coming back next week with their new track and the Black Soshi concept to perform their comeback stage! Check out their awesome performance below! http://www.youtube.com/watch?v=cYZfb5QQ7Xg Also making a return was SNSD's Yuri. She had been laid low by swine flu and had her schedules cut for a week, resulting in Sooyoung and Seohyun taking her spot alongside Tiffany last week on Music Core. It was great to see her back to her bubbly self and she looked stunning in pink alongside Tiffany. Stay tuned to Black Soshi's comeback performance on next week's Music Core! http://www.youtube.com/watch?v=Td2kDvjlQbc
