I guess my bias list leans with maknaes, main dancers, rappers or main vocalists. lol. 
P.S.: It doesn't mean that when I don't have a bias from a group from the list, I don't listen or know them. I know most of them and listen to their songs but don't have any bias although in a few groups listed, I barely know or listen to them ^^
