Tangled Up in Blue was one of the featured songs on his best album Blood on the Tracks.   It is song which looks back at former relationship and themes of loss, love, regret, and the how the passing of time changes us.   It is a bit of a creative piece, but the lyrics stick with us over time:

Early one morning the sun was shining
I was laying in bed
Wondering if she'd changed at all
If her hair was still red
Her folks they said our lives together
Sure was going to be rough
They never did like Mama's homemade dress
Papa's bankbook wasn't big enough
And I was standing on the side of the road
Rain falling on my shoes
Heading out for the East Coast
Lord knows I've paid some dues
Getting through
Tangled up in blue
