The Highest Selling Rappers are OVER 30 Yet "YOUTH" is running the game?

As I've said in past post Hip Hop is at a crossing point. The genre is 30 years old and is moving away from the "Youth" Oriented mentality that dominated it early in it's inception. Proof of this is last year in 2009, The two highest selilng rap albums were Eminem who is 37 and Jay Z who is 40. None of the rappers the youth co-signed sold more than these two emcees. Fast Foward to 2010 and dispite Drake having a Big opening week for a debut, 37 year old Eminem will easily surpass his sales next week. Kanye West is pushing his mid-30's and will easily outsell Drake Also. Whenever Jay Z decides to drop again, he will outsell Drake. Lil Wayne was born in 1982 so he's pushing 30 himself. The point is the YOUTH IS NOT running Hip Hop, the fact is Hip Hop is maturing and when 37 and 40 year olds outsell everyone, it proves the Youth is losing it's hold on the game. I'm actually happy to see this cause Hip Hop is really growing up.
(Do you think this is true? , Do you think the older rappers have a bigger grasp on hip hop, rather than the younger rappers?) "Just leave your answer under the comments"
