Unlike traditional pop songs, "Livin' Underwater" functions more as a transitional piece or a "segue" within the larger context of Wildflower . Critics on Album of the Year highlight how the album’s 21 tracks are designed to flow into one another like a continuous DJ set.

The heart of the track lies in its primary sample: Paul McCartney’s . As noted by reviewers at The Quietus , McCartney personally sanctioned the use of the track, allowing The Avalanches to manipulate his 1971 hit into something far more ethereal. By slowing down the source material and layering it with shimmering synthesizers, the group creates a "woozy" sensation that mimics the feeling of being submerged in water. Technical Composition and Atmosphere
