"King Apathy III"

I listened to Dr. Byrds & Mr. Hyde yester-day and noticed that there's a contrast between sections of "King Apathy III."  Compared to the verses of the song, the "So I'm leavin' for the country..." sections are slower, and the instrumentation is less intense.  This musical reprieve illustrates that departure and the narrator's "rest[ing] my head."

"Pretty Polly"

I realized to-day that there are some features in the title phrase of "Pretty Polly" that illustrate this prettiness from a linguistic point of view.  The two words alliterate; they have the same number of syllables, so there's a balance; and they rhyme.
