Known as 'Asia's Pop Group', F(x) is slowly wining over the young girls that rule the K-Pop world, one sing-a-long song at a time. F(x) is a young 5-member girl group who debuted in September with their first single, La-Cha-Ta. Now the girls are releasing their first mini-album titled Chu which is also the name of the new single. A very similar style to La-cha-Ta, Chu is very much a song made for 12year olds, but is still catching the eye of the 'olds' because it's so catchy. Check out Chu bellow.
