Honestly, pretty terrible. MGK is not someone i'd call skilled in terms of lyricism and flow. It feels amateurish at best and he never rides the beat in a memorable way. I'd say the instrumental is pretty good, though i can do without the overly loud, distracting Ronny sample. A few of the shots he takes at Em could be argued, but he doesn't bring anything new to the the discussion or spins it to add his own personality or flavour, making it a pretty dry track with choppy flows and cringey, petty lyricism.
He tried though, I guess and ngl, i got the hook stuck in my head even though the thing shouldn't have one in the first place.
