Carrie's duet is currently #18, I'm expecting it to go at least top 5 on iTunes tomorrow due to the Idol performance
That means Idol will have given her two hits in the past two weeks, they do wonders for her.
Also, strange thought, that means ITYS will be Carrie's 13th top 50 hit on the Hot 100, she could technically release a greatest hits CD if she wanted to
Obviously she won't, but still, that's a lot of hits for the small amount of time she's been in the industry!
