UK is always that way. And the label decide the premiere. It's only premiered about a month and a week before release. That's standard. 1D did the same, as did Little Mix and Alexandra too. I mean she premiered in january (at a live gig) and it wasn't out till March

A mix of the UK and US charts in terms of preorder and premieres would be better imo. Also she's doing a big radio tour and tv promo too. It's to get people to know she's back and buy GH.
