Hmm. So Niamh has probably the best song choice - let's see what she does with it. Jodie's could go either way, though vocally she should be absolutely fine. Jessie and Rachel have two of my least favourite songs ever (because let's face it, Rachel'll be singing the Whitney Houston wail-fest version), and, well, we'll have to see how they sound - I'm slightly more optimistic for Jessie, but who knows. Samantha, I'm actually cringing already...
