Kanye West is an artist that values collaboration.

We've heard it his music, and we've heard about it, too -- like when he flew a who's who of artists out to Hawaii to help him work on his 2010 masterpiece, My Beautiful Dark Twisted Fantasy.

Now, it seems like Yeezy is at it again.

Yesterday, the final version of his track "All Day" dropped, just days after he premiered it at the BRITs. Though it features Theophilus London, Allan Kingdom and Paul McCartney, and Velous and French Montana are the credited producers, way more people had a hand in this creation. A look at the official credits for the song, which Def Jam sent to MTV News, reveals an amalgam of 21 musicians whose work went into writing and producing the track.

Again, this isn't the first time Kanye has done this -- MBDTF's "All of the Lights" credited Rihanna, KiD CuDi, Tony Williams, The-Dream, Charlie Wilson, John Legend, Elly Jackson (La Roux), Alicia Keys, Elton John, Fergie, Ryan Leslie, Drake, Alvin Fields and Ken Lewis on additional vocals -- but it doesn't make the collection on "All Day" any less striking.

Meet the cast.

Kanye West

You know him.

Paul McCartney

You know him, too. He was in the Beatles and has been working with 'Ye a bunch lately. That's him whistling at the end.

Kendrick Lamar

Did you see this one coming? Maybe they worked on this while they toured together last year? I wonder what K. Dot's specific contributions were.

Velous

Velous talked with MTV News last week about producing the track, and is also credited as a writer under his real name, Tyler Bryant.

Karim Kharbouch

French Montana is referenced with his real name in the credits (which is interesting, particularly, since Kendrick is credited as Kendrick Lamar rather than Kendrick Duckworth). In addition to a writing credit, French produced on the song.

Puff Daddy

That's right. Puff was credited as a producer here.

Travis Scott

The G.O.O.D. Music artist and producer was given an additional production credit on the song.

Cydel Young

Better known as Cyhi the Prynce, the talented G.O.O.D. Music signee hasn't had his solo shine, but is seemingly still a valued member of the crew by the founder.

Ernest Brown

The main thing I found with a quick google search was a former pro basketball player with this name. Maybe Yeezy had him around to help him exercise? We're going to need a little more time on this one.

Victor Mensah

Vic Mensa was featured on Kanye's "Wolves," and clearly they worked together multiple times for the upcoming album.

Allan Kyariga

This is Allan Kingdom's real name. The Canada native got a huge look with this feature.

Mike Dean

Mike Dean is best known as a producer and mixer, who has been around for a couple decades and worked with Kanye frequently in recent years. He got a co-production credit, as well as a writing one.

Che Pope

Che is a G.O.O.D. Music-affiliated producer, according to his Twitter.

Noah Goldstein

Goldstein is an engineer that has worked with Kanye, Jay Z, Nas and 2 Chainz (including on "Birthday Song"). He got a co-production credit, as well as a writing one.

Allen Ritter

Ritter is a producer and singer who works frequently with Vinylz and has produced for Drake, Nicki Minaj and more. He got an additional production credit, as well as a writing one.

Mario Winans

A producer, writer and singer, Winans scored a huge hit in 2004 with "I Don't Wanna Know," and though we've heard from him less in recent years, clearly he's still making moves behind the scenes. He got an Additional Production credit, as well as a writing one.

Charles Njapa

Known to fans as 88-Keys, the producer and rapper has worked with Kanye multiple times, including on "Stay Up! (Viagra)."

Malik Yusef Jones

You may remember the G.O.O.D. Music poet said that Kanye's album sounds "like a pair of Timberlands" late last year.

Patrick Reynolds

Plain Pat has worked extensively with Kanye and Kid Cudi, particularly early in their careers. He got an additional production credit, as well as a writing one.

Noel Ellis

The track contains a sample of Noel Ellis' "Dance With Me," and he was given a writing credit.

Charlie Heat

The producer also worked with 'Ye on Pusha T's "Lunch Money."
