Linds at no. 46.
I think for Jesse to win this, he's going to start having to do current songs. iTunes throws an entirely different spin on voting, giving power to people who do reinventions rather than covers. Mostly it takes away some power from the frenzied moms at home.
If Lindsey keeps doing what she's doing, she has a legitimate chance at winning—iTunes is rallying behind her like they did Dia.
re: who Christina will save, I think it's probable that she'll save Sera or Moses, yeah. Sera for the I'm Going Down moment, and Moses for her... strange adoration she seems to have for him. I still think Ashley deserves it more though. As for Blake, I'm pretty certain he'll save Erin.
