I see no problem with someone saying that "my criteria is the following. I value it because... And due to that criteria, I find Good Charlotte to be better than the Beatles. I understand that this is a minority position."
Now people might find your criteria ridiculous and that is their right but it's your right to feel as you do. The cost is just that people might not value your opinion in discussions. It doesn't make you inherently wrong. There is a social cost, one that is mitigated somewhat by you explaining yourself.
