Hes highly intelligent and this is his life. He remembers this stuff like you'd remember riding a bike. He doesn't remember all. I've asked him plenty of stuff that he can't recal or doesn't know. Its really more about asking the right questions and getting his answers. and I had years to do that. He never really wrote any songs, he sung them on the fly mostly either while hyped up on drugs or through the fear of being tortured. The mind runs quick when they do that, and when done consistently it makes one able to think faster normally. This is why he usually gets top score when he plays online games like star wars battlefront. He used to take screen of how he kept getting first. and ive seen how quick his reactions are, not just in games but when you ask him a pertinant question he respnds like right away, don't even really need to take a moment to think about it. Like its all already gone through his head. So yah he thinks better than the average person.
