While “Girl’s Power” has a more cute and innocent sound, “Speed Up” is a uptempo pop dance track.
Kara’s promotions in Japan have been very successful. They previously released their full album “Super Girl” last November and recently reached triple platinum, selling over 750,000 copies.
They have also recently began their KARASIA tour on February 18 at Seoul Olympic Park. From there, they are scheduled to hold concerts in Hong Kong, Japan and other Asian countries.
