i think with a lot of those artists, they found other ventures that made them more money compared to just making music. and they were able to be just as competitive and creative. music isn't their primary concern anymore. for example dre and headphones, diddy and vodka, jay-z apparel.

all the names listed above above are DJs and have used live musicians on their tracks. these new producers tho, i'm not even sure they'd know how to play a vinyl record or even track live instruments on their beats. real live instruments, not just a synth patch playing thru a weighted midi or pad.
