#Stained
Note that whilst "Anomaly" has been confirmed to be the working title of "[[The Way Out Is Through]]", the final titles for "Rotation" and "Stained" have not been revealed; "[[Underneath It All]]" may be the final title for the latter, based on its prominent lyrical use of the word.

* The descending wah guitar melody played during the intro of "We're In This Together" is similar to the wah guitar that occurs roughly halfway into "Complication".
* The three note motif used in the first part of "The Great Below" is briefly quoted in the ending of "We're In This Together" two semitones down and at a slower tempo. This melody may also be used to end the guitar solo, and may be played on a background synth at the end of the first verse of "The Wretched".
* "The Great Below" climax melody and bassline are reused for a quiet bridge in the leftover/outtake "[[And All That Could Have Been(song)|And All That Could Have Been]]".* A sampler keyboard pad created from Reznor's voice is used for "The Frail" and leftover/outtake "[[Leaving Hope]]".
* Rapidly ascending, very chromatic guitar riffs are prominently featured in "Somewhat Damaged", "The Day The World Went Away", and "The Wretched".
* Mike Garson's piano improvisations are prominently featured on "Just Like You Imagined", "The Way Out is Through", and "Ripe (With Decay)".
* The lyric "underneath it all" from "The Way Out is Through" is repeated in and used to title "Underneath It All".
* The lyrics "now you know/this is what it feels like" are the refrain for both "The Wretched" and leftover/outtake "[[The Great Collapse]]".
* The lyric "[[Nothing Can Stop Me Now|nothing can stop me now]]" appears in "La Mer" and "We're In This Together", albeit translated into French Creole on the former and altered to "none of them can stop us now" on the latter. The same phrase was previously used in "[[Piggy]]", "[[Ruiner]]" and "[[Big Man With A Gun]]" and would recur later in "[[Sunspots]]".
* The lyrics of "The Great Below" and "Underneath It All" are similarly composed, and both use the refrain "all I do/I can still feel you".
* The lyric "could have been" is prominently used in "The Wretched", "The Great Below" and "And All That Could Have Been".
