On Monday, Jay-Z dropped, "Glory," a love letter featuring coos and cries from his and Beyonce’s newborn, Blue Ivy. The song will debut at #74 on Billboard’s Hot R&B/Hip-Hop Songs chart, making the days-old child the youngest person ever to chart. This is also Jay-Z's 107th Billboard entry, which perfectly mirrors Blue's date of birth, 1/07—a perfect bit of serendipity for a family who loves numbers so much.
