I read something interesting in the print edition of Rolling Stone (I'm home sick today, so I don't have my usual sources). When Bjork is asked if she has any guilty pleasures, she mentions "Hot Blooded" by Foreigner. But where she gets advanced is when she says about the song, "...that's not a guilty pleasure, that's just a good tune." That is an advanced point of view. There should be no such thing as a guilty pleasure in an advanced person's life. If you like something, you like something, and you don't have to distance yourself from your true feelings by pretending that you feel guilty about them. So good for Bjork!
But she's still overt.
