Dylan was good at adding several really good lines in a mish mash of poetic word salad.

“Dylan was good at adding several really good lines in a mish mash of poetic word salad.“

Lennon and McCartney as well.

I'd suppose that when composing a song, an author sometimes has no idea where the line he writes down came from. But, if it moves him, there's no way he/she'll abandon that string of words (or tones). If the composition becomes popular, then it's moving other people in some way too.

Mish-mash it may be, but there's always the hope that time will eventually give it context and enable a more readily discerned common understanding of the thoughts behind it.
