While it's not a traditional poem, the lyrics of the song are very poetic, exploring themes of love, loss, hope, and despair in a way that feels very much like a piece of poetry.
Specifically, the lyrics could be classified as:
* Free verse: The song doesn't follow a strict rhyme scheme or meter, allowing for a more natural and conversational flow.
* Confessional poetry: The lyrics delve into deeply personal experiences and emotions, offering a raw and vulnerable look into the speaker's psyche.
* Existential poetry: The song grapples with big questions about life, death, and the meaning of existence, prompting introspection and contemplation.
Ultimately, the categorization of the lyrics is subjective and depends on the individual's interpretation. However, its poetic language, emotional depth, and philosophical exploration certainly qualify it as a piece of work with significant literary merit.
