Generate AI-curated Spotify playlists from Telegram using OpenRouter GPT

🎵 AI Spotify Playlist Generator (Telegram → Spotify)

instantly create a curated Spotify playlist based on a single song recommendation sent via Telegram. This workflow uses an AI Agent to generate similar tracks, creates a new playlist, sends you the link immediately, and then populates the playlist in the background. ✨ Features

Instant Feedback: Creates the Spotify playlist and sends the URL back to your Telegram chat immediately, before the AI finishes processing.

AI Curation: Uses an AI Agent (via OpenRouter) to act as a "Greatest DJ," generating 25 songs similar to your input.

Smart Searching: Automatically searches Spotify for the generated tracks.

Error Handling: Includes logic to skip tracks that cannot be found on Spotify.

Rate Limiting: Includes a wait loop to ensure Spotify API rate limits are respected during population.

🛠️ Prerequisites

To use this workflow, you need:

n8n: An active instance of n8n.

Spotify Developer Account: You need a Client ID and Client Secret to authenticate the Spotify node.

Telegram Bot: A bot token created via @BotFather.

OpenRouter Account: An API key for OpenRouter to access the LLM (Language Model).

    Note: You can easily swap the OpenRouter node for an OpenAI or Anthropic node if preferred.

🔄 How it Works

Trigger: You send a message to your Telegram Bot (e.g., "Daft Punk - One More Time").

Create Playlist: The workflow immediately creates a new empty playlist on your Spotify account named with your username and the prompt.

Reply: The bot replies to you with the link to the new playlist.

AI Generation: The prompt is sent to an AI Agent which generates a JSON list of ~25 similar tracks and artists.

Processing:

    The workflow splits the list into individual items.

    It loops through every item.

    It searches Spotify for the specific Track + Artist.

    If found, it adds the track to the playlist.

    It waits 1 second between adds to prevent API errors.

⚙️ Setup Instructions

Credentials:

    Set up your Telegram API credentials in the Trigger and Send Message nodes.
