Money has always been a dominant theme in Lil Wayne's music, but his relentless lust for it is also what's driven him to acquire so much of it that he's become completely complacent. When MTV asked Wayne about Drake's Take Care sales last November, his response was: "We rich as shit, so numbers and record sales don't matter to none of us."
That's fine. "Money On My Mind" is probably his best song ever, but listen to the haters, Weezy. Ignoring sales figures is one thing, but Wayne uses that same rationale to dismiss critical observations, and he needs to understand how drastically the conversation surrounding his work has changed. Public opinion moved from "best rapper alive" in 2008 to top YouTube comments like "Lil Wayne sucks" in 2012, all the while his net worth has only increased.
If Wayne would stop using his wealth as a crutch and realize that lackluster output is tarnishing his legacy, maybe he'd be motivated to do better.
