Wouldn't be surprised if Kelly falls a lot over the night. The usual nightly decreases combined with the loss of #1 exposure is going to be deadly.
I don't mean to sound like a Negative Nancy, but I think once she loses the top spot she won't return. So, I'm hoping she gets #1 soon, because it's going to be damn hard after she falls.
Regardless though, I am so happy this is doing what it is. Even if it peaks at #2 and never returns to the top of iTunes, it is a smash that is going to have massive longevity and help the album, which is all that really matters.
That'll be less competition on itunes for several weeks then.
