This is funny. It's a slight dig at those folks (of which I'm sure the author is one, or the self-effacing sort) who want every one of Bob's incoherent ramblings to be 'deep'.

"Because I grew up in a world where nothing that Mr. Dylan ever did was too insignificant not to be worthy of serious intellectual scrutiny, I immediately understood that this was no ordinary, haphazardly arranged, string of colored lights. It had to contain a deeper meaning."

A lot of Bob's work is the intellectual equivalent of a paltry string of Christmas lights. Your outlook with figure if that's an insult or a compliment.
