“Glory” F. B.I.C. (Blue Ivy Carter)

    You’ve probably already heard the news that Jay-Z and Beyonce welcomed their first child into the world this weekend. But if you haven’t, said child is a baby girl who goes by the name of Blue Ivy Carter. And wouldn’t you know it, she’s already got her first guest feature on one of her dad’s tracks. After some touching rhymes that detail how the couple had some “false alarms and false starts” along with just how proud Jay is to be a dad — “My greatest creation was you” — you hear the young Carter crying at the 3:20 mark. Who knew Jay had it in him to be this sweet. Stream the Neptunes-produced track below. [RR]
