See, it's about the experience, and sensing sort of. It's not really that much of a metaphor I don't think, except for that fact that he's a Luddite, and thinks that things should go back to the way they were before, lol. That's basically all he says in his interviews, etc. I believe he's very interested in history and the past. I think that's mostly what his over-arching message is. "Things should be like how they were before"
You see it all over his music and in his songs. It's always the past, the past, the past. Even his style of music, why do you think he decided to become a blues musician? Anyway, I've been listening to him on and off since I was really young. I think he's pretty cool, but for the aforementioned reasons above, he kind of irks me at times.
Actually, I almost think ISTP too, which would explain how at times he almost seems like he has Fe, but yet doesn't really seem Fe-dominate. I don't know where the hell ENFP came from. That's probably more likely.
