There is no argument or debate. Lil Wayne is THE best rapper alive. His beats are sick, his lyrics and metaphors are ridiculous and clever as hell. He makes stupid money and lives like a boss. He does all the drugs and shit he wants and does not give a fu*k what anyone thinks of him. People can hate on him for being popular and just making music that will be played on popular radio stations and crap. Bullsh*t. For every song he creates that is purely for public appeal, he has an equally sick mixtape or freestyle for his dedicated fans. Hes not a sell out and he legitmately cares about what he does and is really fu*king good at rapping. Theres nothing anyone can say, hes the best rapper alive right now. Best rapper of all time is another debate. If you don't think hes the best alive, you are dumb, this is not an argument but it is FACT.
