On September 11th, SISTAR took home their first ever Mutizen trophy for their latest track, "So Cool", on SBS's 'Inkigayo'.� The girls immediately burst out into tears as they expressed their gratitude towards their fans. SISTAR said, "We won #1 for the first time while promoting our first official album. We promise to become a SISTAR who strives to improve." Right after they gave their award statement, the girls looked unable to control the tears streaming down their faces. A representative of Starship Entertainment revealed, "The members won #1 on KBS's 'Music Bank' last year on December 17th with 'How Dare You', but they couldn't receive their trophy on stage due to a special broadcast. They received their trophy a week after." "They've finally formally received one on stage, and they couldn't stop their tears at the thought of such a moment." Congratulations to the girls!
