"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."

"Blue"

The last section of "Blue" exhibits anaphora:

Blue the rainbow, blue the trees

Blue the raindrops, blue the seas

Blue is ev'rything around me

The repetition here indicates this entirety ("ev'rything around me").
