"Reanimator" is a collaboration between Joji and Yves Tumor. The song explores themes of emptiness, disillusionment, and the desire for escape. In Joji's verses, he describes feeling suffocated by a world filled with hollow materialistic pursuits. The sun, which is usually associated with brightness and warmth, is portrayed as something dim and unremarkable. The choir singing about extravagant and luxurious things only adds to the emptiness Joji feels. He metaphorically compares this feeling to drowning and sinking, as if being overwhelmed by this superficial reality. Yves Tumor's chorus adds a different perspective. He acknowledges that it's not up to him to change the world or others' perceptions of it. He implies that if indulging in superficial pleasures makes someone feel good, then who is he to judge? They can continue doing it all night. However, he also highlights that this indulgence does not define him and that it's alright if others find solace in it. Overall, the song seems to explore the struggle between wanting to escape from a shallow reality while recognizing that others may find comfort within it. It delves into the complexities of personal satisfaction and the acknowledgment that different people find fulfillment in different ways.
