"Our recent pop-music icons, even the most radical ones, like Björk or Caetano Veloso, often have to present themselves as happy and make positive work because they have such a large young fan base to whom they feel responsible. They can't be too negative. Now, criticism is basically a negative act. As you know, critics are neither pop stars nor popular. They are the gripers. But someone has to speak up and say no to this and yes to that."
