Create lyric posters from Spotify tracks with Musixmatch and OpenAI

Description

Turn a song into a ready-to-hang poster, by using Musixmatch and AI

This n8n workflow turns a song title and artist name into a gallery-ready poster by combining Musixmatch lyric intelligence with a tightly controlled AI art direction pipeline.

At its core, Musixmatch is used to identify the correct song and retrieve official lyrics, which then drive a highly curated image-generation prompt and final poster artwork.

What this workflow does

Trigger via chat
The workflow starts when a chat message is received.
The user provides a song title and artist name.

Identify the correct track with Musixmatch
The Musixmatch “Match track by metadata” node is used to:
Resolve ambiguities in song titles
Confirm the correct track
Retrieve a stable commontrack_id
This ensures all downstream steps reference the correct song.

Retrieve full lyrics from Musixmatch
Using the confirmed commontrack_id, the Musixmatch lyrics endpoint fetches the official song lyrics.
Lyrics are treated as authoritative source material for creative interpretation.

AI Agent selects and interprets a lyric
A dedicated AI Agent:
Selects one single-line lyric (strictly enforced constraints)
Analyzes its emotional and thematic meaning
Interprets mood, tension, and implied narrative
The lyric becomes the conceptual anchor of the poster.

AI Agent constructs a high-fidelity image prompt
The agent outputs a fully structured, production-ready image-generation prompt including:
Song metadata (reference only)
Emotional interpretation
Visual style choice
Composition and layout rules
Typography and legibility constraints
Quality and design guardrails
No drafts, explanations, or partial output are allowed.

Generate the final poster image
The completed prompt is passed directly to the image generation node.
The result is a high-resolution, A4 portrait poster designed to feel intentional, modern, and gallery-ready.

A single poster image (1024×1536, A4 portrait ratio)
