No Hate for that. Its just 2 different industries, Mainstream vs. "underground" (I hate that term) I listen to all types of hip-hop. The conceptual type of rap seems to have a lot more of what you are talking about; samples, meaning, etc. I love both. CLASSIFIED FTW.
I don't agree with your point about producing their own beats. ALOT of artists have producers, that doesn't mean they aren't part of every song from beginning to end.
