No, he's not. If for whatever incomprehensible reason you enjoy his music then that's your opinion - whatever. But he is an a fucking abysmal lyricist. His rhymes are the very definition of basic except in extremely rare cases on his older mixtapes where they could be described as mediocre at best. His range of topics is about as broad as an anorexic Ethiopian child and about as compelling as an R.L. Stein novel. Lastly, he flows like a constipated old man who hasn't consumed anything besides Saltines for three days. Those three metaphors alone were better than anything Li'l Wayne has ever come up with. Ever. He is a talentless abomination who has sold off every last grain of artistic integrity.
Listen to ANY of the following musicians/groups and tell me you still think that Li'l Wayne is a skilled MC.
Cunninlynguists, Jurassic 5, Qwel, Surreal, Insight, Sleep, Non Phixion, Problemaddicts, Del, Slug, Binary Star, Big L, Big Pun, Eyedea, Louis Logic, Murs, Sweatshop Union, Necro, People Under the Stairs, Main Flow, Doomtree, Rakim, Blue Scholars, Common Market, Celph Titled, Apathy, Hieroglyphics, Hilltop Hoods
Diverse, Pep Love, Slick Rick, the Grouch...
And these are just names that are so substantially better that they immediately put Wayne to shame (that right there was a fucking Weezy rhyme, did you see what I did there?), there are countless more who slaughter him who I didn't even mention and it's already a long fucking list.
