Jay-Z and Beyonce's Baby entered the Billboard Charts at 1 week old!

Blue Ivy Carter is the youngest person to enter the Billboard charts which also possibly makes her the youngest person to make music history. Jay-Z released the song, Glory, about Ivy Blue with his wife Beyonce on January 9th 2012. 

It featured the sound of Blue's cries at the end, for which she is credited. The song immediately became a viral hit, and entered the Billboard chart at No.74. 

Its 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." 

This did stir a quite a bit outrage, however, it should be noted that this record in itself doesn't give Ivy any sort of head start in the music business, it isn't exactly something she can put on her resume. It's simply a loving gesture from parents, that they can guilt her with every time she doesn't want to clean her room.
