Keeping the stickers on your hat looks really dumb. It's like if you don't know what to do with the tags after you buy clothes. Anyway I'm off topic here moving on.

This is in no particular order at all. Up until Big Bang it was in order of favorite groups however after that it was just who came into mind at that moment. Some of these groups would be higher and others would be knocked down a peg.
