Nastradamus is the fourth studio album by American rapper Nas. The album includes one of the earliest shots fired in the soon-to-be epic Jay-Z/Nas feud. On Nastradamus' title track, Nas raps "You wanna ball till you fall? / I can help you with that / You want beef? / I could let a slug melt in your hat". The album also includes the single You Owe Me featuring Ginuwine.
