Crystal Bowersox is undeniably talented and she has quite a following. But the young mother, aka Mamasox, shouldn't think that she's got the competition in the bag, so says Simon Cowell. I agree. Siobhan Magnus slays songs and she brings something new each week. That being said, Crystal Bowersox's cover of the Rolling Stones "You Can't Always Get What You Want" was great, per usual. She reminds me of Janis Joplin so much. I just love her.
