"Nights on Fire"

"Higher" in the lines "Knowing only love can take us higher / Higher" in "Nights on Fire" is sung with a melisma (D C# B both times), and while the pitches descend (contrary to the word's meaning), the extra notes emphasize the comparative nature of the adverb (more notes for a greater degree).

"Blue"

I listened to New World again yester-day and noticed some more small points.

The lines "And if I could only spread my wings / I'd hear the sound of dreams" in "Blue" (written by Sebastian Santa Maria) may contain a nod to "Summertime," specifically its line "Then you're gonna spread your wings and take to the sky."

"It's Alright with Me"

The Zombies' social media accounts have been posting about "It's Alright with Me" quite a bit lately, and as I was thinking about the song yester-day, I had a few realizations about it.

The recurring line "But if you want to stay around and love me" is sung to far fewer pitches than the surrounding lines (it simply alternates between Eb and F), and in a way, this narrow scope reflects the "stay[ing] around."

That the first verse and the third verse use the same sound for their rhymes ("door" with "floor" and "poor" with "door," respectively) poetically represents the narrator's limited means.

The phrase "mess around" in the first line may indicate Ray Charles' influence, specifically his "Mess Around," in which this phrase frequently recurs.  "It's Alright with Me" is in C minor, and if I'm not mistaken, "Mess Around" is in Eb major, so the two songs are in relative keys.

"Brief Candles"

I listened to Odessey and Oracle yester-day and noticed some significance in the structure of the line "Finds he needs her more because she's no more need for him" in "Brief Candles."  The words "needs," "more," "more," and "need" form a chiasm (since they're different parts of speech, however, it's not an exact correspondence).  That the order of the words is inverted from one half of the line to the next illustrates the complete opposites here.
