I like it, and wasn't expecting too either.
It's very current but without crossing the line of just being totally generic and forgettable. Not an absolute smash, but I could see it taking off here.
I agree that she'll be the one that manages to do well solo. We've already seen her dabble with success and if this also becomes a hit then she'll be on somewhat of a roll. I don't see it for Heidi at all and the jury's still out on Jade but I see her more as a musical headliner unless she lucks out on killer material.
