I see what you mean, but compared to most Rap, including what he had done before, he was speaking on shit that you NEEEEEEEEEEVER hear in Rap. Yeah, he was being slightly immature by putting down the "immature" folks, but I don't think him saying "30's the new 20" meant "30 year olds should still act 20"...it was more saying that "20 is supposed to be your prime, but I'm letting y'all know that 30 is your prime in a different way than you're used to hearing."

He did it in typical arrogant Jay fashion of course, and some of his wording was off like "better broad"...but serious, who in Rap ever made a hit song where they bragged about NOT sagging, not having a flashy watch, not buying out the bar, not putting on tints, etc. etc? It basically gave 30+ folks something to be proud about, instead of feeling like they have to keep up and be trendy like the young folks out there.
