The song "Formaldehyde" by the band Editors explores themes of obsession, longing, and the destructive nature of love. The lyrics depict a narrator who is willing to have their love dissected and analyzed in order to be understood by their partner. The use of formaldehyde, a preservative used in the preservation and study of biological specimens, serves as a metaphor for the intense and somewhat toxic nature of their love. The narrator asks if every heartbeat burns with the same intensity in their partner's blood, symbolizing the desire for reciprocation and mutual passion. Despite the intensity of their love, the narrator hopes that they can overcome any obstacles and escape from the overwhelming flood of emotions and desires they are experiencing. The repeated refrain of "I'll never let you go" expresses the narrator's determination to hold onto this love, no matter the consequences or pain it may bring. The song suggests that the narrator is consumed by this all-encompassing love, comparing themselves to a specimen drowned in a bath of formaldehyde. This imagery represents the drowning sensation of being deeply immersed and overwhelmed by the emotions and intensity of their relationship. Overall, "Formaldehyde" explores the longing for deep connection and understanding within a relationship, while also acknowledging the potentially destructive nature of such intense emotions.
