Just 48 hours after the birth of his and Beyoncé's royal heiress, Blue Ivy Carter, Jay-Z served up this postpartum anthem with a lilting Neptunes beat, a news-breaking disclosure about a previous miscarriage ("All the pain of the last time/I prayed so hard it was the last time") and a sample of baby Blue herself. "Glory" is a hip-hop "Isn’t She Lovely," mixing exultant proud-papa sentiments with brand-consolidation braggadocio: "A pinch of Hov, a whole glass of B." But the mood is reflective. "Everybody go through stuff," Jay tells his daughter. "Life is a gift, love, open it up."
