SISTAR were on a winning streak this week by taking the #1 trophy on 'M! Countdown' and 'Music Bank' for their new title track "Touch My Body" and held an interview backstage at 'Music Bank'.

Soyu shared what she believes to be the secret to their wins, "I think it's thanks to the composers who write good songs for us and our agency's support."

Hyorin also gave her two cents, "Because we promote a lot whenever summer comes around, our music receives love as summer songs. Our personalities suit summer songs and they're refreshing, so I think that's effective [for our success]... We're really thankful."

Soyu talked about how they fulfilled their promise to perform a funny dance if they win #1 on 'M! Countdown', "To be honest, I didn't event know we were #1 candidates. It was an impromptu dance... We have to fulfill our promise to write our names in the air with our butts this time, but I think it'll be hard to win because there's such strong competition."

Congrats on your wins this week, SISTAR!
