“Expensive” is the only track on Slime Language that doesn’t include Thug himself as a vocalist, instead Thug’s sisters, Dolly White and HiDoraah being the authors of this song. The track is produced by Billboard Hitmakers, a production duo who have previously worked with Thug in tracks like Relationship (ft. Future), Harambe or Floyd Mayweather (ft. Travis Scott, Gunna & Gucci Mane).
