I've always littered my songs with jokes. You might need to dig a little deeper to find the humor, but I would totally object to being some kind of distraught personality. I've never tried to attach myself to that.
People expect not just songwriters but all personalities to pontificate about their egos.
I think a master craftsman is someone who is unpretentious. He has a physical object in front of him and, while he works with a higher aim, he doesn't let his personality get in the way of his art. It's simply about the task at hand and to make it as functional and necessary to the world as he can.
