I've been called out on this before, and I probably won't stop doing it ever. As much as I love Kpop, and I do at that, I have problems finding new bands or getting into their music, until I have a bias for that band. I don't pick a bias until I have a reason to like them, and that reason usually comes from seeing them in a drama first. I think it's possibly because I tend to just appreciate them as a collective until I know one of them enough to love him individually.
A prime example of this is my history of liking Super Junior.
