My first thought was “Suzanne” by Leonard Cohen, but that’s already been mentioned.
“Tangled Up in Blue” has always been one of my favourite Dylan poems/songs because of the intense description of characters, particularly the woman and also her husband “he started dealing in slaves (drugs?) and something inside of him died”… so vivid.
And Taxi especially his description of himself:
Oh, I’ve got something inside me,
To drive a princess blind.
There’s a wild man, wizard,
He’s hiding in me, illuminating my mind.
Tell me you don’t get an idea who that man is, from those four lines alone, never mind the rest of the song.
Why yes, I do love singer/songwriters, how can you tell?
