According to Windswept "Age Ain't Nothing but a Number" bears a striking resemblance to Caldwell's song. "Age Ain't Nothing but a Number" is Aaliyah's most controversial song within her discography due to its lyrical content about dating someone older. The lyrical content of the song raised eyebrows because the song was written and produced by R.Kelly. After the release of the song a marriage certificate emerged stating that a fifteen year old Aaliyah and a twenty seven year old R.Kelly were married.
