I saw the Japan Times mention "we don't even want to count KARA as a K-Pop act anymore, since their transformation to AKB48-clone seems to be complete, both image-wise and music-wise".
While I don't agree 100% with everything they said in there, it is definitely true that they've gotten rid of most of their K-Pop style. Ah well.
Jet Coaster Love is now Platinum for Chaku Uta Full (was Gold), which, combined with its Gold for PC, makes for a total of over 350,000 downloads.
Go Go Summer is now Gold for Chaku Uta Full! These are July certifications, so figures should be going up ; )
