Classics are timeles.Lets just see how many people will care to hear these rappers 20-30 years from now.What alot of people dont understand.Is that the rappers from the 90,s grew up on music from the 70,s and 80,s.So they cared about production and originality.That was there advantage.The producers back then grew up being taught how to actually make beats.Yes they sampled.But the music had feeling.Throw on The Chronic,Doggystyle,Ridin Dirty,Ready to Die,Outkast first 3.Then throw on any album from the past 5 years.Thats not Kendrick,Cole,and compare them.Its not even close.Most of the producers from the albums i named.Have a musical background/knowledge.There not going to tell the public that.Nowadays these new producers have limited knowledge.And they dont really care to have it.Thats a huge reason why region sound is not in abundance anymore.
