Just days before their new album arrives, N.E.R.D has dropped another new song, "Don't Don't Do It!," which features Kendrick Lamar.

And as Pharrell revealed Wednesday on Zane Lowe's Beats 1 radio show, the introduction line of the song was written by none other than Frank Ocean, who is uncredited on the track.

"He is the art of no compromise, no concession, and very colorful with it,” Pharrell said today. “And that’s what, I feel like—that’s what is very interesting about his journey."

The powerful new song was inspired by the shooting of Keith Scott and a number of other unarmed black men killed by police officers, as referenced in the song's lyrics.

As we previously reported, N.E.R.D's No One Ever Really Dies is out this Friday. It features a number of other guest appearances, including André 3000, M.I.A., Wale, Gucci Mane, Ed Sheeran and of course, Rihanna, who appears on their previously released lead single "Lemon."
