TBT - Kara's "Rock U"

Released: July 25, 2008

This was the very first Kara single featuring Hara and Jiyoung, who were added to the group as original member Sunghee had left to study, and this addition truly did wonders for them. I suppose it helped that they switched concepts as well, as "Rock U" wasn't too similar to their debut songs. You can say whatever you want about the MV, and I think it's kind of cute although a bit alarmingly childish, but the song is so catchy. I can't help but shamelessly love it.
