i think he has a memory problem, you know some rappers can write the best raps but cant remember the words..its for this reason, during concert performances, Ross always has the music playing while yelling out the lyrics so u think he's not just miming, instead of just having the beat play like other rappers do. If u can remember his performance of 'Magnificent' with roots on Jimmy Fallon Latenight, he forgot some of his words then as well....
