How old Boosie sound? Big Sean sound like a grown man? or Pat Piff? or that one southern dude screaming on the WW3 track, think his name was Yung Wun?
I don't know who Pat Piff is but Boosie, Big Sean or Yung Wun don't sound like children. Those dudes sound like Grown Men. Especially Yung Wun and Big Sean. Boosie has a high pitched flow but even when he was 16 I didn't think he was actually that age. Sounds like a grown man with a high pitched flow.
And if Diggy doesn't have that trait that'll make you forget his age so what? I still aint getting an answer for why the age is that important. Can't be about content or believability cuz there's hundreds of rappers that aint about what they spit.
Well i'm speaking from a 24 year old's perspective. And for me its tough to get passed listening to a Justin Beiber or a Diggy because I simply can't relate to what they're talking about. That's what sets a Diggy a apart from a LL Cool J, or a Lil' Wayne or a Shyheim. The latter rappers help you forget their age. Diggy reminds you when he speaks.
