"This Will Be Our Year"

Yester-day, I heard a sloppy cover of "This Will Be Our Year" where the singer got half of the words wrong, but referencing the correct words led me to a realization.

I noticed that there are slant rhymes in the verses:  "the warmth from the sun" with "the darkness has gone" and "smile for me, little one" with "all your worry days are gone."  In a way, the imperfect nature of these rhymes illustrates the current absence of "the darkness" and "all your worry days."  Even poetically, they're incompatible with the present situation and time.
