You've never discovered something and felt the indescribable, joy-inducing draw of its appeal? Listened to some music and immediately jived with it? Blaming familiarity bias and "old man yells at clouds" is a disappointingly small-minded critique. It's the opposite: I've lived long enough to thoroughly experience the joy of newly discovering something that feels like it fits me perfectly; conversely, I've tried to appreciate other things enough times to know never to waste my time trying again. Especially for the sake of others.
I've learned that liking things behaves a lot like attraction. It has no reasoning or logic, it happens organically, and when you know, you know. Thus, I would never deign to pretend to like something I've found I don't.
