He was a really talented song writer.
A great song.
He was great, but he also busted his butt writing them. He said every song he ever wrote came from “blood that turned into notes on the page” meaning he went through hell writing them.
There’s one documentary on Youtube that is really good, this one below, where he says he “wore out the rug” working on songs without sleep for days. To me that’s what “genius” really is, it’s people who can keep going like that and just by sheer force of will come up with tremendous things. They don’t stand for failure even to the point of harming themselves
