Sampling "Hide And Seek" seems pretty obvious, and really he doesn't do a whole lot with it. I could see someone really chopping up her vocals and making something dirty out of it, but DeRulo wants to go the emotional route with this one, and he does a decent job. "Whatcha Say" is a song about wanting to make it up to your girl after getting caught cheating, presumably by becoming famous enough that she forgets you're an asshole. I applaud that logic.
Not a whole lot else to say about it. It's got the feel of a song that's either going to really catch on and become huge or just fall off the face of the earth. I'm hoping for the former, because there's far worse on the radio right now.
