Eminem, Lil Wayne, Kanye West, Drake's Collabo: Check Out A Preview Here!

'Forever' is inspired by forthcoming LeBron James documentary 'More Than a Game.'

It's one of the greatest collaborations in hip-hop history: Eminem, Lil Wayne, Kanye West and Drake on the same song. "Forever" was inspired by the forthcoming LeBron James documentary "More Than a Game" — and you can check out a preview right here!

Earlier this week, Young Money president Mack Maine told MTV News about the track, titled "Forever." An early version of the song — featuring Wayne, Drake and Nut Da Kidd and produced by Boi-1da (Drake's "Best I Ever Had" and "Uptown") — has already hit the Internet, but this week, the version with some of hip-hop's hottest MCs is expected to debut.

"They redid it, it got mixed over the weekend, now it's getting mastered," Maine said Monday.

"Forever" will appear as part of a collection of tracks inspired by the film (due in theaters October 2), with the soundtrack coming September 29 on Interscope Records. Polow Da Don will executive produce the set, which will also include songs by T.I., Mary J. Blige and Young Jeezy, according to Rich Paul, who works with James as a part of their marketing company LRMR.

Paul said that "Forever" was originally only going to include Drake and Kanye West.

"It was done, it was just Drake and Kanye, and then they went back and got two more prolific talents, and it just made it even crazier," Paul told MTV News late Tuesday. "They blessed Drake crazy."

The song came together when Gee Roberson, an executive at Atlantic Records who also manages West and helps oversee the careers of Drake and Wayne, visited LeBron during the playoffs in May.

"He came over and played this — it was me, LeBron and Maverick [Carter, James' manager]," said Paul, who will co-executive produce the project for James' camp. "And he played the track. It was hot. It went right with the movie. It was like perfect for a moment that you want to be forever. And when he decided to put Wayne, Drake, Kanye and Eminem on it [together], it just makes it better. It's one of those songs fans will really want to hear forever. It's that type of feeling."

Lil Wayne has long expressed a desire to rap alongside Eminem on a track — and now, he's done it.

Mack Maine also revealed the song may be getting a last-minute addition.

"There's gonna be an unexpected feature on the hook," he said. "Right now, we have three different R&B singers writing the hook to see who comes up with the best one. I'mma be shocked. So I can't tell you who it's gonna be."

On the original, Drake performs double duty, rapping and singing the chorus. Plans call for Drake, Wayne, West and Em to shoot a clip for "Forever" next month in New York, Paul said, directed by Hype Williams.
