The studio version of Kanye West’s new track ‘All Day’ has been unveiled on US Radio this afternoon after it was premiered last week at the Brit Awards.

That particular version was heavily bleeped-out on UK TV due to the watershed – but this version is the final clean studio version.

The track features Theophilus London and rising St. Paul rapper Allan Kingdom on vocals, and there’s also a bizarre acoustic guitar solo towards the end (confirmed as Paul McCartney whistling). But after that it goes bat-shit crazy again.

As far as Kanye tracks go – this is certainly the best we’ve heard from him in quite sometime.

It’s taken from Kanye’s recently announced new album ‘So Help Me God’, which is expected sometime this year.
