"Like Someone in Love" is followed by the techno-tinged "Big Time Sensuality" in an "intentionally startling" leap. An "anthem to emotional bravery," it contains lyrics described as "simple but passionate", concerning Björk's relationship with her co-producer Nellee Hooper. The songs "The Anchor Song", "One Day", and "Aeroplane" draw on what Björk refers to as her more "academic, clever side". "One Day" also presents a sudden shift of mood, featuring a "gently pulsing bass" that builds into an "itchily impassioned, housey pop euphoria." "Aeroplane" is one of "Debut"s most musically complicated pieces with off-kilter arrangement from Oliver Lake; its backdrop is inspired by exotica music. This song is also about Thrupp, written when he was living in the United Kingdom and Björk still lived in Iceland. "Come to Me" features a "hazy musical backdrop of raindrop synths, padded drums and sweeping strings"; lyrically, it explores a "sensually intense need to nurture." "Violently Happy" is the most hardcore techno track on the album. In the song, over "brisk house beats" Björk sings in a stammering fashion, as she "struggles to express feelings of excitement so intense she seems on the brink of leaping out of her skin." As a gesture to inexpressible feelings, the song samples one syllable and " it into a stuttering vocal tic." The closing track "The Anchor Song" is the only one in the album solely produced by Björk. One of the three songs to appear on her first demo cassette of 1990, it features Oliver Lake playing the saxophone, in an arrangement that replicated the "ebb and tide of an ocean's peaking tops, an image reinforced by Björk's fiercely patriotic lyrics."
