 Rick Ross drops by to say hi , keeping his appearance so brief that I can 't help but wonder what he 's even doing here . Justin Vernon inexplicably bookends the thing , pushing his falsetto into Antony range on the outro and muttering befuddling lyrics that have nothing to do with the rest of the song . All this over the straight @-@ up funkiest beat Kanye West has made in years , a rippling electro push @-@ pull that adds an effortless strut to his recent progged @-@ out chilliness . But all that other stuff fades into the background when Nicki Minaj shows up . [ ... ] She 's a whirlwind of energy , showing her full repertoire of nutso voices and kicking the living fuck out of the beat , sounding like she 's having an absolute blast the whole time . "
