Just because you think it's funny doesn't make it untrue. I personally don't like Em, he's just a hit maker, who talked about beating women, and killing people. Yet people think he's a top five rapper.
Also all the albums you put down were commercials success, Country Grammar was just as successful if not more so than those albums.
I'll stop you before you say rap doesn't need to be commercial success for it to be top five. Well your top five has 5 commercially known rappers. If you want message, and content, then anyone you named would not even be top five. There are a !@#$ ton of under ground rappers, past, and present who have had better rhymes, better beats, and better messages.
So you fall into the same trap as everyone else by naming mainstream rappers. So you shouldn't be Loling someone's taste because you don't think it's top five material. Especially when you hear more Nelly in rappers now-a-days then you ever hear Pac, Nas, Biggie etcetc Hell not many even sound like Kanye.
