Being a fan isn't how many plays you have on last.fm, or how many songs you have, or knowing middle names.
It's about passion. It's about the excitement. It's the breathlessness when the person you idolise most in the whole world walks onto a stage. It's the little shriek when you spot them on the cover of a magazine. It's the rhythm and melody and harmony, and it's every single little note that sends fire rushing through your body and floods your organs with euphoria. It's knowing that this is what you love, this is your passion.
