He leaked the track yesterday (Dec. 10) to promote his Hallucinagens mixtape, which gives an interesting glimpse into the life of a pop song. Some verses are the same, some are new, some are even from the rapper's verse on Ciara's 2013 single "I'm Out," suggesting that the song had been in the works at least since then.
