Korean idol. . .
Artists from SM Company are popular all over the world. . . But it is said that the requirements are quite strict. . .
YG's is also very popular. . . GD, 2NE 1 is very popular in Korea. . .
JYP artists are very free. . . 2PM and Miss A are also very popular. . . But the popularity is not so high recently, probably because there is no new album.
BEAST and 4minute are both from CUBE. . .
According to the testimony of my Korean classmate, CUBE is slowly replacing JYP in Korea.
