Crystal and Katelyn are where it's at, period. I want to like both Didi and Lacey (and, caveat, did enjoy the beginning of her song and her tone, but then it went to hell in a handbasket), but I'm not a huge fan of their voices. As for the others, I simply do not like them. I don't like their vocal stylings, I don't like the nasal, I don't like the delivery, I just don't like these voices.
Oh, and Paige?
That's actually one of my top five favorite Kelly songs ever. So, yeah, just don't.
Crystal? Katelyn? That's my top two right there.
(Psst! I LOVED Katelyn's "The Scientist." I do think she should have ended it on a really soft note, but I thought she did a beautiful job with it overall.)
