Kanye West told fans The Life of Pablo would be released Friday after he shared his new song, "30 Hours," along with an updated tracklist for the album. Obviously, Friday has come and gone, and though fans will be disappointed they didn't get the album the day he promised it, they should know it was pushed back for a good reason. Early Saturday morning, Kanye tweeted Chance the Rapper was behind the delay because they were working to get "Waves" on the album. "It’s Chance's fault the album not out yet… he really wanted Waves on that Bitch… we in the lab now," he said. For his part, Chance assured fans it was the right move. "I fought everyone to keep Waves on the album. I spent all night finishing it. The world is better because of it." Check out the tweets below.
