“King of Hearts” has a hypnotic beat while the mediocre singer sounds like she’s in heat on the track. Throughout the entire thing Cassie sounded reserved; there wasn’t a note worthy section at all. And that’s understandable being that she’s not exactly the greatest vocalist in the world. With that said, “King of Hearts” is perfect for the clubs and on a loud stereo, aside from that, it’s just another generic euro dance song. By the way, the music video is rather blahh. You’re only seeing a half naked Cassie looking rather model-esque as she usually does.
