Everyone is God. :-) So, why not Dylan?

But I digress. "Whiter Shade of Pale" is definitely one of the great seminal songs of all time.

I think Dylan considerably exceeded Lennon/McCartney or Jagger/Richards as a poetic songwriter...but...at the same time it is true that the Beatles and the Stones were both exceptional at what they did in their own unique fashion. Dylan was a great admirer of what the Beatles did with melody, chording, rythm, and vocal harmonies. As far as he was concerned, they led the way in those areas from '64 on, and it changed everything. He led the way in poetic imagery, serious lyrical content, and in bridging roots music with popular music...and the Beatles were aware of that. The Stones led the way in blues-based "angry young white boy" rock music. They were all masters of their particular craft, and they all borrowed happily from one another. It wasn't a competition, it was a mutual explosion of creativity.

Their fans can fight over it after the fact if they want to... :-)

"All Along the Watchtower" as recorded by Jimmy Hendrix (but written by Bob Dylan) was another very significant song.

As for WWII era zeitgeist, I would nominate Vera Lynn's "White Cliffs of Dover", "Lili Marleine", and Edith Piaf's marvelous signature song, "La Vie en Rose".
