Generally, there are hot dances in the mv of Korean groups, except for the lovely images, which are all Korean dance music. Sexy actresses like Lee Hyo Ri and Chae Yeon all have hot dances in their MVs, and the groups include LPG/Beg/Rainbow/Secret/Miss A/After School. In particular, there is a piece of music in Song after School that is used for dancing. Personally, I like T-ara, but they are much cuter and sexier to dance: just like at the beginning.
