"Who Would've Thought" is more of a duet between Keef and Future than it is a standard guest spot. Future handles the hook but both artists deliver their verses with Auto-Tuned croons.

The lyrics are all about reaching the pinnacle of success and beginning to question everything around you, which is more contemplative than the aggro drill music for which Keef has made himself known.

"Who would've ever thought that I would grind like this?" Future asks on the hook. "Who would've ever thought diamonds cost this much / Who would've ever thought n-as can't be trust / Who would've ever thought the girl wouldn't give it up?"

As for where the track will end up, it won't be Keef's long-delayed upcoming album Nobody--which is finally out Dec. 16--because he posted the tracklist earlier today. But when Future is on one of your throwaway track, then your album must be fire.
