* Vinyl does not come autographed. * "It's called Chemistry because I was trying to find a word—also, it might be one of the songs on the album—but I was trying to find a word that really described the whole thing," Clarkson said. "Because I didn't want everyone to think I was just coming out with some, 'I'm angry, I'm sad' [album], just one or two emotions. This album is definitely the arc of an entire relationship. A whole relationship shouldn't be just brought down to one thing. So there's the good, the bad, and the ugly kinda thing going on. Chemistry can be a really amazing sexy, cool, fun thing, but it can also be very bad for you. So that's why I named it Chemistry. I thought it was the perfect title to describe the entire album."
