Mostly DBSK, but I like them all. But yeah, there are so many. SJ, SHINee, 2PM, SNSD, After School, 2NE1, T-Ara, BEG, Big Bang, ZE:A. I like at least one song from most of the groups. But I probably follow DBSK and ZE:A the most. Yoochun is my number one bias; I love Changmin (DBSK), Junyoung, Jonghyun of SHINee, GD, Rain, Siwon and Sungmin of SJ, Taecyeon and Chansung of 2 PM. Those are my favs in Kpop.
