Jay-Z's Kanye West Produced 'Jockin Jay-Z' Leaks In Full Online

The final edit of 'Jockin Jay-Z', the first track from US rapper Jay-Z's forthcoming Blueprint 3 album, has leaked in full online.

The song, which has been produced by Kanye West, was aired for the first time last week when Jay-Z joined West on stage in New York.

The finished version of the track includes Jay-Z's attack on Oasis guitarist Noel Gallagher, where he raps: "That bloke from Oasis said I couldn't play guitar/Somebody should have told him I'm a fuckin' rock star."

He then mocks the Oasis track 'Wonderwall', singing: "Today is gonna be the day that I'm gonna throw it back to you.”

The rapper also voices his support for US democratic presidential hopeful Barack Obama in the song.

West is one of a number of producers who are expected to contribute to Blueprint 3, which is due to be released next year.

As previously reported on Gigwise, Timbaland recently suggested that he was behind the whole production.

But Jay-Z played down Timbaland's comments, calling them “premature” in an interview with Rolling Stone.
