The voices that I can make the most are those of Nicole (who has a particular voice) and Gyuri. Yet for me SeungYeon is the most beautiful voice in the group and it's hard sometimes to recognize. (T_T)
I have known KARA in June 2009, during a broadcast with SNSD "COME TO PLAY!) dating from March 2009 And I was not too attached to the group like beginning, but by dint of listening, I've loved & Now, KARA is in my top 5 favorite.
