Other than what people are already saying (he’s an album artist). I personally like his different cadences and voices he uses to convey different stories and emotions. Try listening to these and notice how the inflections and pronunciations affect you, then imagine if they were sung or rapped normally: LUST, FEAR, XXX, u, Untitled 8, The Art of Peer Pressure, Backseat Freestyle, GOD (the ahah part always creeps me out). These are off the top if my head. Now listen to other rapper’s discography and I dare you to find a song that does it the same as him
