{blackbabes} Jay-Z's New Song 'Glory' Features His 'Greatest Creation' Blue Ivy

Blue Ivy Carter is only two days old and already she is featured on her proud dad's latest record. But really, how else would Jay-Z and Beyoncé introduce their baby to the world?

Jay-Z posted the latest track, "Glory feat. B.I.C.," (listen below) on his Life + Times website Monday. The rap concludes with sounds of a newborn crying.

Elsewhere during the cut, Jay makes some heartbreaking, as well as some sweet, revelations. "Last time, the miscarriage was so tragic," he raps. "We was afraid you disappeared, but nah, dear, you magic."

Another verse reveals that Blue Ivy, a.k.a. "the most beautiful girl in the world," was "made in Paris," just before Knowles "shot an album package."

"People haven't ever seen Jay this happy or proud," a source tells PEOPLE.

And you can hear that joy all throughout the song: "The most amazing feeling I feel," he raps. "Words can't describe what I'm feeling for real / Baby, I paint the sky blue / My greatest creation was you."
