According to Billboard's website, Blue Ivy Carter has become the youngest ever to hit the R&B/Hip-Hop Charts. Three days after her birth, her father (rapper Jay-Z) recorded a track titled, "Glory" and posted this on his official website. The infant makes her debut at the end of the track with a few short cries. Shortly after, the song made a climb up to No. 74 on the R&B/Hip-Hop Chart.
