If your signature hit is a song you dislike, then of course you're going to mention such every time someone asks about it. Every artist does promo and continuously answers the same questions with the same answers. Formality upsets people?

First time I heard the song I thought it was great. After a dozen plays, it became average. I don't even listen to it anymore.
