Super Junior’s Ryeowook, Lee Teuk, Eunhyuk, Donghae, and other members participated as lyricist and composers. Big Bang’s G-Dragon, Taeyang, and Wonder Girls, SS501, and other groups began to compose lyrics and so on.
Big Bang’s G-Dragon is the most successful example.
The popular Big Bang’s “HARU HARU“, “LIES” , Seungri’s ”STRONG BABY” , Daesung’s trot song, “LOOK AT ME, GWISUN“, “DIRTY CASH“, and more were all his works.
Half of Big Bang’s works went through the hands of G-Dragon. Critics said that they are the “evolving idols” and that’s the difference between the other idols’ success.
