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. 2. 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 commontrackid - This ensures all downstream steps reference the correct song. 3. Retrieve full lyrics from Musixmatch - Using the confirmed commontrackid, the Musixmatch lyrics endpoint fetches the official song lyrics. - Lyrics are treated as authoritative source material for creative interpretation. 4. 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. 5. 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. 6. 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) - Features: - One carefully chosen lyric line - Clean, modern typography - High-end contemporary poster design - Subtle film grain - Fully legible text and metadata --- Requirements - Musixmatch API credentials - Track matching and lyric retrieval - OpenAI API credentials - Language model for creative direction - Image model for poster generation --- Use cases - Creating lyric posters for personal collections - Album or song promotion visuals - Editorial or social media artwork - Print-ready music-inspired posters - Exploring visual interpretations of song lyrics
