Well, that didn't take long. Thankfully.

Just a week after a snippet of a new Kendrick Lamar verse on Kanye West’s "All Day" floated around the 'net, the full version has arrived.

The track features some Yeezy rhymes from the original, plus a new K. Dot verse. The Compton rapper goes in on the track using the same flow that Kanye employs, and is lyrically tenacious -- as usual.

We don't know when 'Ye's upcoming album So Help Me God will drop, but this version comes just a month after Kendrick dropped his sophomore major label album, To Pimp A Butterfly.

Some of the material for the album was drawn from experiences he had while on tour with Yeezy in 2014.

“I’m feeling all these things while I’m on tour," he said of personal difficulties he dealt with, and outlined on songs like "u." "I gotta get off stage and almost face the madness and get all these calls. It’s real man, three of my homeboys -- that summer time -- was murdered.”

“It’s definitely survivor’s guilt, a lot of the album has that survivor’s guilt. How can I be a voice for all these people around the world and can’t reach them like I want to? And they’re the closest to me? That’s a trip."

“And when I was on that tour bus and things is happening back home in my city or in my family that I can’t do nothing about; it’s out of my control, I put it in God’s hands,” he continued. “I couldn’t understand that. And that can draw a thin line between you having your sanity and you losing it. This is how artists deteriorate if you don’t catch yourself.”

It seems Kendrick, in the time since, has caught himself. And, luckily, Kanye caught him, too, for this joint.
