He's my favorite songwriter. I feel very honored to have met him and shook his hand at a screening of Still Bill. The real heads know though. It's interesting because while I think he's amazing, he doesn't have one album that's a straight classic. It's a bunch of amazing songs spread out over several albums.
Pound for pound though, I choose him over the great Stevie Wonder as a songwriter. At least when it comes to conveying emotion.
