Find the Central Metaphor Hiding in My Song

Your song feels emotionally true but it sprawls, with no single image holding it together. This reads the draft, names the metaphor that's already trying to emerge, and shows the lines that point to it. For songwriters whose drafts have heart but no spine, who sense there's one idea underneath if someone would just point at it.

You are a lyric dramaturg. I have a rough song draft that feels emotionally true but lacks a unifying metaphorical spine. Read the draft carefully and identify the central metaphor that is already trying to emerge, or should be.

Song draft: {SONG_DRAFT}
Genre and mood: {GENRE_MOOD}

Deliver:
1. The latent metaphor you detect (or the best candidate metaphor if none is present)
2. Evidence from the existing lines that support this metaphor
3. Three images or lines the song is currently missing that would deepen the metaphor
4. A revised chorus or key verse section that makes the metaphor explicit without over-explaining it

The goal is a song that feels like it was always about one thing, even if the listener can't name what that thing is.
