spotify-dl schedule-stop    # Stop the background task

💡 Persistence (Note)

The --background flag spawns a detached process that survives terminal closure on Linux, macOS, and Windows. It does not require PM2 or any external process manager. Logs are kept at ~/.spotify-dl/schedule.log.

Note: The process will stop if the computer is restarted. For reboot-persistence, use your OS's native tools (crontab for Unix, Task Scheduler for Windows) pointing to the spotify-dl download command.

Advanced options

spotify-dl download --dry-run # Preview without downloading spotify-dl download --template "{artist} - {track}" # Custom filename template


## Architecture

The tool uses a client-side architecture that runs entirely on your machine:

User's Machine ├── Spotify API (metadata only - legal) ├── YouTube Search (find matching audio) ├── YouTube Download (audio stream) ├── FFmpeg (audio conversion) └── ID3 Tagging (metadata embedding)


**Key Components:**

- **Spotify API Client**: Fetches track metadata (artist, album, artwork)
- **YouTube Downloader**: Searches and downloads matching audio
- **Audio Processor**: Converts to MP3 with FFmpeg
- **Metadata Embedder**: Embeds ID3 tags and album artwork
- **Rate Limiter**: Prevents API quota exhaustion
- **Cache System**: Reduces redundant API calls

> [!CAUTION]
> **LEGAL DISCLAIMER: PERSONAL & EDUCATIONAL USE ONLY**
>
> This tool is intended strictly for **educational purposes** and **personal use**.
> - It uses the Spotify API for metadata only.
> - Audio is sourced from third-party services (YouTube).
> - Downloading copyrighted material without permission may violate the Terms of Service of Spotify, YouTube, and your local copyright laws.
> - The developers of this tool assume **no liability** for any misuse or legal consequences arising from the use of this software.
> - **By using this tool, you agree to take full responsibility for your actions.**


## Troubleshooting

### FFmpeg Not Found

```bash
# Install FFmpeg first
# Ubuntu/Debian
sudo apt-get install ffmpeg

# macOS
brew install ffmpeg

# Windows - download from ffmpeg.org and add to PATH

Authentication Failed

Verify your Client ID and Client Secret are correct
Reconfigure: spotify-dl config
Make sure your Spotify app is active in the developer dashboard

YouTube Download Errors

Some videos may be geo-restricted or age-restricted
The tool will skip failed downloads and continue with others
Check logs in ~/.spotify-dl-logs/ for details

Rate Limiting

The tool implements smart rate limiting
If you hit limits, wait a few minutes and try again
Consider reducing concurrent downloads: -c 2

File Locations

Config: ~/.spotify-dl/config.json
Cache: ~/.spotify-dl-cache/
Logs: ~/.spotify-dl-logs/
Downloads: ./downloads/ (or custom path with -o)

Performance Tips

Optimal Concurrent Downloads: -c 3 (default)
- Too high may cause rate limiting
- Too low is slower
Audio Quality: -q 320 for best quality
- 320kbps = highest quality
- 128kbps = smaller files, lower quality
Cache Usage:
- Cache is automatic
- Clear periodically: spotify-dl clear-cache
Playlist Organization:
- Use separate output folders for different playlists
- Example: -o ~/Music/Playlists/Workout
