Erm, just introducing a korean boy-band. They are also known as DBSK / THSK (Tohoshinki by the Japanese), TVXQ (Tong Vfang Xien Qi). Their name translates to "Rising Gods of the East". Initially marketed as an "acappella " group, most of TVXQ's music is mainstream K-pop.
Starting from left is Micky Yoochun, Xiah Junsu, Hero Jaejoong, U-Know Yunho and Max Changmin
Oh, and by the way, I'd uploaded some of their songs. If anyone's interested, you can download them.
