Justin Timberlake Records With Marcus Mumford

'I don't know any other world where we would have the opportunity to collaborate like that,' he says of the song they recorded for the Coen brothers latest.

We already know Kanye West's not feeling"Suit & Tie,"
 but Justin Timberlake is giving him a second chance with another superstar collabo.

The singer recently revealed that he's recorded a song with Mumford & Sons singer Marcus Mumford for the new Coen brothers film JT's starring in, "Inside Llewyn Davis."

"Ok I can tell you this. There's a Coen brothers film coming out soon that I was lucky enough to work with Oscar Isaac and Carey Mulligan," Justin told England's Capital FM.

"And coincidentally I did work with Marcus Mumford on the soundtrack, so I became very good friends with them."

The unnamed track features Timberlake, Mumford, famed producer T-Bone Burnett and progressive bluegrass band the Punch Brothers.

Timberlake co-stars alongside Mumford's wife, Mulligan, in the film about the 1960s folk scene. "Marcus and myself we all kind of worked on the music together and I don't know any other world where we would get the opportunity to collaborate like that but it was so much fun," said Timberlake. "Not only will that be a great movie, but the music to it will be fantastic."

In the same interview, JT revealed that there's a very good reason why a number of songs on his upcoming third solo album, The 20/20 Experience,
 are twice as long,
 or longer, than the average three-minute pop tune.

"When we were making the record I said, 'If Pink Floyd and Led Zeppelin can do 10-minute songs and Queen can do 10-minute songs then why can't we?' We'll figure out the radio edits later,'" said Timberlake, who recently released the eight-plus minute single "Mirrors."
