Kanye West's 'All Day' studio version officially released on iTunes

After a bunch of leaks and some live performances (Brit Awards included), Kanye West released the official studio version of his new track "All Day", to be included in his upcoming new album "So Help Me God". The rapper made the song available on iTunes and it costs $1.29.

"All Day"'s studio version features Theophilus London and Allan Kingdom, while at the end of the song you can hear Paul McCartney whistling. McCartney whistles - apparently - a re-recording of a song McCartney wrote in 1969 that was inspired by a Pablo Picasso painting of a guitarist.

Before the release via iTunes, "All Day" was premiered on L.A. radio station Power 106 and New York station Hot 97, during the afternoon of March 2.

"So Help Me God" still has no release date, but west shared the album's artwork - four calligraphic Ms connected in a diamond.
