The hitmaker’s new album is the hip-hop equivalent of an All-Star weekend. Major Key is a wildly enjoyable set of outsized radio rap whose guest list includes Nicki Minaj, Kendrick Lamar, Drake, JAY Z, Nas, Future, Travis Scott, Bryson Tiller, Lil Wayne, Fat Joe, Jadakiss, Busta Rhymes, Big Sean, J. Cole, Jeezy, Wiz Khalifa, Wale—and somehow, so many more.
