Kanye West's The Life of Pablo didn't arrive as promised Friday, but the rapper said it was for a good reason: Chance the Rapper was in the studio doing some last-minute work on a song called "Waves," which was left off the final and then reconfigured Pablo track lists.<br />However, Chance fought for "Waves" to be included on the album.<br />"I fought everyone to keep Waves on the album.<br />I spent all night finishing it.<br />The world is better because of it," Chance tweeted.<br />The Chicago rapper then posted a photo of West's handwritten 17-song Pablo track list with "Waves" unnumbered and squeezed between "I Miss the Old Kanye" and "FML."
