Well, I have to listen to it a few more times to actually decide, but right now all I can say is that it is no "Only Girl (In the World)".
I hope the single isn't a huge indication of what the album sounds like. It is dark, though. Well, it has a dark undertone. It reminds me of Marina & The Diamonds "Radioactive". The more I listen to it though, the more I like it. I hope I love it soon.
