Theme Song (Underneath) (Unreleased)

Billie Eilish's unreleased track "Theme Song (Underneath)" delves into the complexities of desire and obsession, painting a vivid picture of a tumultuous relationship. The lyrics convey a sense of longing and vulnerability, as the narrator grapples with the intense emotions that come with being infatuated with someone who may not reciprocate those feelings. The repeated phrase "It's killing me" underscores the emotional turmoil and the destructive nature of this unrequited love.

The song's imagery is both haunting and intimate, with lines like "Pull them close then whisper run" and "Stole your keys now you can’t leave" suggesting a push-and-pull dynamic. This reflects the narrator's internal conflict between wanting to possess their love interest and the fear of losing them. The metaphor of being "underneath" someone who is "six foot three" highlights the power imbalance in the relationship, where the narrator feels small and powerless, yet irresistibly drawn to their partner.

Billie Eilish's signature style of blending dark, moody themes with ethereal melodies is evident in this track. The lyrics explore themes of control, vulnerability, and the intoxicating nature of forbidden love. The line "Pull my hair it’s truth or dare" suggests a willingness to engage in risky behavior for the sake of feeling alive, while "Olly olly oxen free" evokes a sense of childhood innocence lost in the chaos of adult emotions. This song captures the essence of a love that is both thrilling and destructive, leaving the listener to ponder the fine line between passion and obsession.
