I Don't Know The Name Of The Song Our Who Sings It.
But Its People Rapping And Its Like Their Talking About Shoes.
And It's a Girl Saying "I CAN BE YOUR LACES"
And It's a Boy Saying "Fresh Out The Box"
It's a New Song That Plays On The Radio.

I can't find the part that says "I can be your laces..." but I found a song that mentions "...fresh out the box." Is the song in the link the song you are looking for?
