Kanye West's been making continuous adjustments to The Life of Pablo since its release this February, altering arrangements, lyrics, features, and more. It looks like his latest album isn't the only LP to receive alterations, though: He's also made changes to 2013's Yeezus. According to Spin, fans have uncovered subtle changes in the Apple Music versions of a few tracks. West's opening phrase on "Black Skinhead" ("For my theme song/My leather black jeans on") now features a more distorted vocal than the original. Additionally, on "Send It Up," he's cut the backing instrumental to his line at the 1:30 mark. Listen to the original versions below, and head over to Apple Music to hear the changes.
