The first we heard of Kanye West’s new single ‘All Day’ was when he mentioned in GQ’s ‘A Brand New Ye‘ interview that certain lines were inspired by Jay Z: “I think about certain lines that I say on my new single, which is called ‘All Day,’ that usually Jay would say, but Jay’s not on there. So I say, ‘All day, nigga, it’s Ye, nigga. Shopping for the winter, it’s just May, nigga. Ball so hard, man, this shit cray, nigga. You ain’t getting money unless you got eight figures.’ Right? Jay would have said that.”  Since then, he debuted the track live at The Brit Awards with an electrifying performance which incorporated UK Grime royalty Skepta, Jammer, Shorty, Krept and Konan, Novelist, Stormzy and Fekky.  A studio version of the track, premiered on  Power 106 and Hot 97 yesterday, has now surface online, which features Allan Kingdom, Theophilus London, and whistling from Paul McCartney.  Stylistically, the track seems to sit mid-way between ‘My Beautiful Dark Twisted Fantasy’ and ‘Yeezus’, and it’ll feature on Kanye’s upcoming album, ‘So Help Me God’.  Stream below via Spotify.
