"Twin Cinema"
The line "They've shown this on both screens" is sung twice in succession and has a harmony each time, and both of those features represent the double in "Twin Cinema."
"Use It"
There's the phrase "the cup of human kindness," which is an allusion to Shakespeare's Macbeth. In Act I, Scene 5, Lady Macbeth fears that Macbeth "is too full o' th' milk of human kindness" (I.v.16).
"Streets of Fire"
The "every" in the line "Let's sully every stage" is pronounced with three syllables rather than the usual two, which emphasizes the exhaustive nature of every.
