Reason #3: There are quite a few guest appearances on the album, but none of them feel unnecessary.
Just like there are more than a dozen producers on Mastermind, there are also more than a dozen guest appearances. Everyone from Jay Z ("The Devil Is a Lie") to The Weeknd ("In Vein") appears here. And yet, it never feels like Ross is shoehorning a guest verse in between two of his verses just for the hell of it. Most everyone feels right at home on the album.
