Description
Who is this for
- Space Enthusiasts & Music Lovers: Discover new music paired with stunning cosmic visuals.
- Community Managers: specific Slack channels with engaging, creative daily content.
- n8n Learners: Learn how to chain Image Analysis (Vision), Logic, and API integrations (Spotify/Slack).
How it works
- Schedule: The workflow runs every night at 10 PM.
- Mood Logic: It checks the day of the week to adjust the energy level (e.g., higher energy for Friday nights, calmer vibes for Mondays).
- Visual Analysis: OpenAI (GPT-4o) analyzes the NASA APOD image to determine its color palette, mood, and subject matter, converting these into musical parameters (Valence, Energy).
- Curation: Spotify searches for a track that matches these specific parameters.
- Creative Writing: OpenAI generates a short poem or caption linking the image to the song.
- Delivery: The image, track link, and poem are posted to Slack, and the track is automatically saved to a designated Spotify Playlist.
