Songfacts®:

• Jay's five-year-old daughter Blue Ivy Carter shows up at the beginning of this song to help her dad out by freestyling some bars. Though hard to decipher, she seems to be saying that the sky is the limit and intends to run the world like her mom.
  
  Never seen a ceiling in my whole life
  Everything I seen, everything is rotten
  Never sit in silence, innocent is Carter
  Innocent we seek them
  I and say we see them
  
  By the end of her verse, Blue seems to get stuck so boosts her rhymes with several "boom-shaka-lakas."
• Blue Ivy first featured on her father's tribute song, "Glory," a few days after her birth. Jay-Z's tribute to his daughter, which includes her cries and coos, made history as Blue became the youngest artist to ever a to feature on a Billboard chart when the tune peaked at #63 on R&B/Hip-Hop Songs.
  
  A few years later, Beyoncé managed to get a guest performance from her daughter for "Blue" on which the toddler's giggles close the song. Blue Ivy also appeared in the music video for her mom's song "Formation."
• After her opening verse, Blue Ivy allows Daddy to step back into the booth and spit some rhymes highlighting his ancestral roots:
  
  I got bloodlines in Benin, that explains the voodoo
  Got poison in my pen, thank god for Lulu
  And thank the heavens for BB, her Creole roots run deeply

  "So I start playing the beat, and I went and just started doing something," Hova proudly said. "I was playing it so long that she went and got the headphones and she climbed on the little stool and started rapping. The pockets she was catching!"
