No offense taken, Jim, not in the least. I share your sentiment about the history of younger, whiter, richer musicians taking credit for the work of older, blacker, and poorer artists. For me, the bottom line is this: give credit where credit is due, and once you've taken something from someone else, show us what you can do with it. That's tradition.
Many years ago, I was asked by a younger musician if it was okay to "steal" riffs from your elders. I told him, "If you're gonna steal, steal from the best."
