Billy Ocean, I got mad respect for you cuz we usually see eye to eye, especially when it come to the WU but you actin like Dre should think like you do. Dre been made it known he don't give a fukk about money, dude ascribes value to much more important things in life. He probably never really made music for the money and the fame, he made it cuz he is creative, he wanted to express himself, be challenged, and speak his mind to people. Thus he would only want to preform if it provided him with such things he values, he says performing the same shyt that he made when he was in his 20s, in a totally different frame of mind doesn't inspire him or provide really any value to his life and I believe him. He didn't ask people to buy his music or tickets to his shows, he simply created it and other people liked it.
He could have created paintings or sculptures and made money off it while getting the aforementioned valuable experiences, that doesn't mean he should go in front of people and create the same piece of art over and over again. Or let's say he made art and never got paid but experienced such feelings or experiences more than he ever did making music I am sure he would prefer that over what he got from music, money included.
