She's not even a week old, but Blue Ivy Carter is already making music history.

Billboard says that thanks to her dad, Jay-Z, featuring her on his new song, "Glory," Blue becomes the youngest person to ever appear on its chart.

Jay-Z released the song about his first-born child with wife Beyonce on Monday, and it immediately became a viral sensation. The song, which credits B.I.C., features the sound of Blue's cries at the end.

The song's refrain is "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."

Now, the song will enter Billboard's chart next week at No. 74.

It's the first child for R&B singer Beyonce, 30 and hip-hop mogul Jay-Z, 42.

The couple revealed to some media outlets that they chose "Ivy" because of the significance of the number "4" or "IV," -- Beyonce and Jay-Z were born on Sept. 4 and Dec. 4, respectively, were married on April 4, 2008, and Beyonce's latest album is entitled 4.
