Bruno Mars releases a reductive album imitating 80’s artists, and he wins album of the year. His album is not the biggest album of the year commercially according to Billboard (Kendrick's album is) nor does it have the biggest hits (That's What I Like peeked at number one for one week.) He still wins for a karaoke album that the much more successful albums by which his album is inspired were not even nominated. In what world does that make any sense?
