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!
