Who is/was the master of conjuring up amazing imagery in their songs?

Leonard Cohen. I can't quite put my finger on it (which I know inevitably sounds like a cop-out)... for reasons that I'm not sure I could adequately articulate, I find a lot of his work to be deeply moving. "The Partisan Song", "Who By Fire", "Last Year's Man", "The Stranger Song", "Avalanche", "If It Be Your Will", "Hallelujah", Chelsea Hotel #2", "Take This Longing", "Famous Blue Raincoat", "First We Take Manhattan", "Everybody Knows", "Suzanne", "Lady Midnight"- so many of his songs are just awe-inspiring to me, and any attempt on my part to explain why couldn't really do him justice. In French (dual French/US citizenship), Jacques Brel, L�o Ferr�, and Georges Moustaki have written some amazingly descriptive songs. Check out Brel's "Les Marquises" and "Voir un ami pleurer", Ferr�'s "La m�moire et la mer" and "La solitude", and Moustaki's "Le facteur" and "Voyage".
