"Heartbeats" is a song originally written by Swedish electronic duo The Knife and covered by José González. The song tells the story of a passionate and intense love affair that starts with a promise and ends in heartbreak. The lyrics depict a night filled with confusion and truth, where both individuals are under the influence of intense emotions. The reference to "divine scent" suggests a strong and irresistible attraction between them. The line "mind is a razor blade" implies that their thoughts and emotions are sharp and cutting, possibly indicating a complicated and volatile relationship. The chorus signifies the desire for emotional support, wanting to "call for hands of above" or seek comfort and stability from a higher power. However, the protagonist realizes that relying on this external support alone wouldn't be enough for them. The song highlights the rush and excitement of the initial stages of love with phrases like "magic rush" and "start a simple touch." It emphasizes the intensity and passion within a short time with the line "One night to push and scream and then relief." The mention of "ten days of perfect tunes" suggests a period of bliss and harmony. However, as the story progresses, it becomes apparent that their love isn't as lasting as they initially thought. The line "We had a promise made, we were in love" indicates that their love was based on a promise or agreement that eventually proves to be short-lived. The second verse adds a dark twist to the narrative by introducing the devil's hand and wolf teeth, which kept them awake. This imagery suggests that they were aware of the destructive nature of their relationship, yet still couldn't resist the allure and passion. In the end, the protagonist realizes that seeking support from external sources is not enough to sustain them. The repetition of "wouldn't be good enough for me, no" emphasizes their desire for a deeper, more meaningful connection. Overall, "Heartbeats" explores the intense emotions, promises, and complexities of a fleeting love affair, ultimately conveying the bittersweet realization that external support is insufficient without a genuine and lasting connection.
