💡 Pro Tip — YouTube’s API quotas can be a bottleneck when you’re pulling data at scale. ScraperNode is a community node with dedicated scrapers for channels, videos, and comments — no quota limits, just structured data.

Description

This workflow creates an AI-powered chatbot that generates custom songs through an interactive conversation, then uploads the results to Google Drive.

This workflow transforms n8n into a complete AI music production pipeline by combining:

It demonstrates a powerful hybrid architecture: LLM Agent + Tools + API + Storage + Async Control Flow

Key Advantages

1. ✅ Fully Automated AI Music Production

From idea → to lyrics → to full generated track → to cloud storage All handled automatically.

2. ✅ Conversational UX

Users don’t need technical knowledge. The AI collects missing information step-by-step.

3. ✅ Smart Tool Selection

The agent dynamically chooses:

This makes the system adaptive and intelligent.

4. ✅ Structured & Error-Safe Design

Reduces failure rate dramatically.

5. ✅ Asynchronous API Handling

Scalable and production-ready.

6. ✅ Modular & Extensible

The architecture allows:

7. ✅ Memory-Enabled Conversations

Uses buffer memory (last 10 messages) Maintains conversational context and continuity.

8. ✅ Automatic File Management

Generated songs are:

No manual file handling required.

How it Works

Here’s the flow:

  1. User Interaction: The workflow starts with a chat trigger that receives user messages. A “Music Producer Agent” powered by Google Gemini engages with the user conversationally to gather all necessary song parameters.

  2. Data Collection: The agent collects four essential pieces of information:

    • Song title
    • Musical style (genre)
    • Lyrics (prompt) - either generated by calling the “Songwriter” tool or searched online via the “Search songs” tool
    • Negative tags (styles/elements to avoid)

  3. Validation & Formatting: The collected data passes through an IF condition checking for valid JSON format, then a Code node parses and cleans the JSON output. A “Fix Json Structure” node ensures proper formatting with strict rules (no line breaks, no double quotes).

  4. Song Generation: The formatted data is sent to the Kie.ai API (HTTP Request node) which generates the actual music track. The workflow includes a callback URL for asynchronous processing.

  5. Wait & Retrieve: A Wait node pauses execution until the Kie.ai API sends a webhook callback with the generated songs. The “Get songs” node then retrieves the song data.

  6. Process Results: The response is split out, and a Loop Over Items node processes each generated song individually. For each song, the workflow:

    • Downloads the audio file via HTTP request
    • Uploads it to a specified Google Drive folder with a timestamped filename

Setup steps

  1. API Credentials (3 required):

    • Google Gemini (PaLM) API: Configure in the two Gemini Chat Model nodes
    • Gemini Search API: Set up in the “Search songs” tool node
    • Kie AI Bearer Token: Add in the HTTP Request nodes (Create song and Get songs)

  2. Google Drive Configuration:

    • Authenticate Google Drive OAuth2 in the “Upload song” node
    • Verify/modify the folder ID if needed
    • Ensure the Drive has proper write permissions

  3. Webhook Setup:

    • The Wait node has a webhook ID that needs to be publicly accessible
    • Configure this URL in your Kie.ai API settings as the callback endpoint

  4. Optional Customizations:

    • Adjust the AI agent prompts in the “Music Producer Agent” and “Songwriter” nodes
    • Modify song generation parameters in the Kie.ai API call (styleWeight, weirdnessConstraint, etc.)
    • Update the Google Drive folder path for song storage
    • Change the vocal gender or other music generation settings in the “Create song” node

  5. Testing: Activate the workflow and start a chat session to test song generation with sample requests like “Write a pop song about summer” or “Find lyrics for ‘Bohemian Rhapsody’ and make it in rock style”
