# Prompt Spines for Lyric Drafts Before Genre Remix Passes > Source: > Published: 2026-10-31 07:43:57+00:00 If your short-form pipeline treats “AI lyrics” and “AI remix” as interchangeable buttons, you will over-generate and under-learn from listens. A **prompt spine** is a typed contract for the lyric pass: it decides which variables reviewers may change later. This note frames lyric spines as an interface, then shows where a genre remix belongs—after the text graph is stable—inside [WAV AI](https://www.wav.ai/). Music information work often studies lyrics and audio as related streams with their own evaluation problems. Open resources such as the [DALI](https://github.com/gabolsgabs/DALI) dataset (aligned lyrics with audio) make that separation explicit. Downstream product tools compress the loop, but your pipeline still needs typed steps: meaning first or arrangement first—not “more AI.” Think of the lyric call like an endpoint: ``` spine = { promise: string, # one-sentence chorus meaning must_keep: string[], # title line / hook fragments sections: ["verse","pre","chorus",...], constraints: string[] # syllable budget, banned clichés, VO overlap rules } → lyric_draft → rewrite(single_named_flaw) → freeze_keepers → (optional) remix_bed ``` | Field | Why it exists | Failure if omitted | |---|---|---| | promise | Gives reviewers a pass/fail besides “feels cool” | Endless vibe arguments | | must_keep | Protects identity across rewrites | Chorus mutates every pass | | sections | Forces structure over sticky one-liners | Orphan hooks with no verse job | | constraints | Encodes picture/VO reality | Beautiful lines that do not fit the cut | ``` brief → build_spine → lyrics_generate → rewrite_once → freeze_keepers → remix_if_bed_gap → ship_max_2_candidates ``` Use the [AI Lyrics Generator](https://www.wav.ai/tools/ai-lyrics-generator) only after `spine` is filled. Cap rewrite to **one named flaw** (rhyme collision, syllable overrun, unclear promise). Multi-knob rewrites destroy causal learning. Call the [AI Music Remixer](https://www.wav.ai/tools/music-remix) only when keepers are frozen and the remaining bug is energy, genre, or instrumental density. Preview under VO. Reject remixes that force lyric rewrites—that is a signal you unfroze the wrong layer. Adaptation permissions are not a model parameter. Creative Commons’ [CC license overview](https://creativecommons.org/share-your-work/cclicenses/) is a practical reference when the source work actually carries a CC grant; commercial releases without that grant still need clearance. Put the rights check **before** public export, same as any other ship gate. It is not a bake-off of generative architectures, and it does not cite product marketing percentages. Treat lyric and remix as typed stages with explicit freeze points—then your failure logs start teaching something useful.
