Good Gone Girl, for the UK market, definitely, as first single.
After that, We Are Golden, even without hearing it, which is a bit presumptuous, but from the snippets and descriptions that also sounds as if it would appeal to UK tastes.
I think Blame it on the Girls has more US-appeal. Rain has a pan-European appeal.
Toy Boy..not a single at all IMO, though I really like it.
Blue Eyes would make a good single and perhaps ought to have been promoted a bit more as lead track from the EP.
