===The Great Below===
This is the original album version. A single synthesizer layer fades in from the end of "[[La Mer]]," ascending in pitch until it is joined by a deep bass melody, doubled by synthesizers and providing accompaniment for an acoustic guitar melody. These synthesizers and the bassline stop for [[Trent Reznor]]'s softly-sung vocals, still accompanied by the guitar melody and joined with new, sea-like atmospheric loops. The lyric, "all of this for you," occasions the re-entry of the synthesized bassline and atmosphere layers, which build as the second verse is sung with harmony. These eventually open up to the climax, featuring a driving bassline and layers of wordless vocal melodies shared with "[[And All That Could Have Been (song)|And All That Could have Been]]," and Reznor's yelled lyrics, which connect the climax into the coda section. Beginning with a new guitar melody, atmosphere layers cycle in as a drum pattern enters and Reznor sings the final lyrics. The line "I can still feel you", and its melody, are referenced later on "[[Underneath It All]]". The drums eventually give way to the fading repetition of atmosphere loops. The song's vinyl mix has a slightly different crossfade with "La Mer."
