I don't think this is as difficult to understand as we're making it.
My money is on the Andreas Carlsson having collaborated with the band (like Max Martin did.)
But just as the Swedish press did with It's My Life, they chose to focus the attention and the credit to the local-boy-made-good at the expense of Bon Jovi. And that's probably why Jon was so unhappy with the Swedish press last time round... looks like they're up to the same thing this time around.
Are they just idiots or can they not translate the most basic information provided by the band that the album was being produced by Jon, Richie and Ebbin again? Or are they selectively deaf to the obvious?

Hopefully, the band will provide the songwriting credits this time. But I'm not going to believe the Swedish papers when they're whole spin is about their own with a good dash of disrespect and misrepresentation of Bon Jovi.
