Playing an instrument doesn't make you any more or less of an artist. Pretty much anybody can find the opportunity to learn an instrument anyway. You can be bad at playing an instrument just as easily as you can be bad at singing. And we're talking about American Idol here. If Idol was called "Let's find the new James Taylor or Carole King" then I would get the importance of it, but since Idol isn't.. I can't say I feed into the whole superiority complex of one who plays. Idol producers want to find someone with 'IT factor' . 'IT factor' is something that you are born with, not something you can learn.
