Anything would have a hard time being a follow-up to "Hollaback Girl," but of all the tracks on her album, I'd say "Cool" is going to have one of the hardest. Gwen has much stronger tracks on her album, and though it will probably be successful for the sake of being Gwen's next single, I think it would otherwise be no more popular than "What You Waiting For" was.
