All Along the Watchtower

[unbibium]

"All Along the Watchtower" is coming up again in my life, this time on a blog.

A blogger argued against fiction's obsession with worldbuilding, and one response states:

For me, three-decker fantasy worlds became obsolete the day Bob Dylan wrote “All Along the Watchtower”, & got the worldbuilding effect in 130 words. For that, you can bet he didn’t “construct” a whole world then pare it down to a couple of perfect indices.

I confess: I don't quite understand the nature of the song.  I've seen the lyrics online, they don't really strike me one way or the other.  They stick in my brain, but don't do much else.
