My wife watches the show so sadly I have seen it many times. I agree with Richard, Bowersox is talented but her style does not appeal to me in the slightest. She is more of a one trick pony, sure she sounds like Joplin but that is all she has.
Have you heard Crystal Bowersox?
If like Janis Joplin or Bonnie Raitt and haven't been watching American Idol, you should go to YouTube and check out Crystal Bowersox.
