A Rust application that automatically syncs a Spotify playlist with songs from Eska Gorąca 20 (Polish radio station hot list).

• 🎵 Web Scraping: Automatically scrapes the current songs from Eska Gorąca 20
• 🔍 Spotify Search: Searches for each song on Spotify using artist and track information
• 📝 Playlist Management: Updates an existing Spotify playlist by:
  • Removing all current songs
  • Adding the new songs from Gorąca 20 list
• 💾 Smart Caching: Caches search results to avoid redundant API calls
• 🔐 OAuth Authentication: Secure Spotify authentication with token persistence

• Rust 1.70 or higher
• Spotify Developer Account
• Spotify Premium Account (for playlist modification)

1. Go to Spotify Developer Dashboard
2. Create a new application
3. Add http://localhost:8888/callback as a Redirect URI
4. Copy your Client ID and Client Secret

1. Copy the .env.dist file to .env:

   cp .env.dist .env

2. Edit .env and add your Spotify credentials:

   CLIENT_ID=your_spotify_client_id
   CLIENT_SECRET=your_spotify_client_secret
   

cargo build --release

cargo run

On first run:

1. The application will open your browser for Spotify authentication
2. After authorizing, copy the redirect URL from your browser
3. Paste it into the terminal when prompted
4. The authentication token will be cached for future use

1. Scrapes Eska Gorąca 20: Fetches the current songs from the Gorąca 20 list
2. Searches on Spotify: For each song, searches Spotify using the artist and title
3. Updates Playlist:
   • Finds your playlist named "Eska Gorąca" (create it manually first)
   • Removes all existing songs
   • Adds the new songs from the Gorąca 20 list
4. Reports Results: Shows which songs were found and which couldn't be matched

• rspotify: Spotify Web API client
• tokio: Async runtime
• reqwest: HTTP client for web scraping
• scraper: HTML parsing
• dotenv: Environment variable management
• serde/serde_json: JSON serialization for caching

The application creates two cache files:

• spotify_cache/.spotify_token_cache.json: Spotify authentication token
• cache.json: Song search results cache

Some songs might not be found due to:

• Different spelling/formatting between Eska and Spotify
• Songs not available in your region
• New releases not yet on Spotify

• Delete spotify_cache/ directory to reset authentication
• Ensure redirect URI matches exactly: http://localhost:8888/callback
• Verify your Spotify app credentials are correct

• Create a playlist with the exact name "Eska Gorąca" (or your configured name)
• Ensure the playlist is in your own library
