A rough version of Kanye West's new single, "All Day," has leaked. The unofficial version sounds to have been recorded by phone.

'Ye's flow is reminiscent of Nicki Minaj's on "Lookin' Ass," and features his signature braggadocious raps.

West told GQ magazine that he plans to release his seventh studio album "most likely in September." He's not 100% positive of the release date, though: "I go back and forth. Like, should it be September or should it be October? Should it be November?"

Update: Although the song was a rough recording, it didn't stop fans from tweeting and causing the song to chart on the Billboard Twitter Trending 140. It was at No. 1 for five consecutive hours.
