I feel you. Its an opinion. And I am also in the sound biz as well so I do have much credit although just by being a musician or sound engineer alone does not give warrant past opinions. I believe Rick Rubin has quoted being not a musician nor does he know much if not hardly anything when it comes to music. He just knows what people want and what sounds good to him. (Spin Magazine) When you don't like an artist, you tend not to listen to them and all they have to offer. Lil wayne holds a different sound and seems to be more polished, maybe due to the fact that he can afford a better producer. I believe that Lil Wayne can outshine those artist on any given sunday so to speak, but I also think the like can do just as good. He has had a rather large following and was considered by many, even before he had a platinum selling album, to be a great rapper. Beyond being great, ie the best, that can only follow opinion, and to me, you have just cited that with no real evidence beyond saying that he is commercial. If you could convince me on style, lyrical play, and the like then I might agree.
It is the goal of any artist to be successful, maybe not with monetary means, but in the fact that they would like to be heard by people.
