Create lyric posters from Spotify tracks with Musixmatch and OpenAI

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

1. Trigger via chat

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

1. 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.

1. 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.

1. 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.

1. 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.

1. 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.

Output

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