Many new dads sing their kids' praises, but few have the chance to rap them. Two days after Beyonce gave birth to the couple's daughter, Blue Ivy Carter, proud papa Jay-Z memorialized "the most beautiful" girl in the world in his song, "Glory." The sound of a baby's cries—reportedly Blue's—ends the loving song, which includes the chorus, "The most amazing feeling I feel/Words can't describe what I'm feeling for real/ Maybe I paint the sky blue/My greatest creation was you. You. Glory."
