It doesn't matter how many times an artist performs a new song or is interviewed, if you don't like them you won't buy into it. Being constantly pushed into the lives of the unsuspecting works two ways, you either lap it up or you ignore it.
Look at how today's artists are exposed to the general public. They make the same music, use the same producers, fake twitter feuds, fake relationships and breakups, go on every talk show they can, make documentaries, make films, they are everywhere, you are exposed to every minute detail of their lives, it is so repetitious. It really is worrying that people are so easily manipulated by it.
