A script to automatically add all songs from a Spotify playlist to your library (Liked Songs).

• Because I don’t see the point of playlists — I keep everything in Liked Songs, but when I transfer tracks from other apps, they all end up as separate playlists
• I just want to

• Automatic Spotify OAuth authorization
• Fetches all tracks from a playlist (including large ones)
• Skips tracks that are already liked
• Adds tracks to your library in batches
• Detailed progress output

• Python 3.6+
• Spotify Developer Account
• Client ID and Client Secret from your Spotify App

1. Clone the repository or download the files

1. Go to the Spotify Developer Dashboard
2. Click "Create app"
3. Fill in:
   • App name: anything (e.g., "Playlist Liker")
   • App description: anything
   • Redirect URI: http://example.com/callback
4. Save the app
5. Copy the Client ID and Client Secret

On first run, the script will prompt you to enter your credentials.

python3 -m venv venv
source venv/bin/activate
python spotify_like_playlist.py

1. A browser will open to authorize the app via Spotify
2. Grant access to the app
3. You'll be redirected to example.com — copy the full URL from the address bar and paste it into the terminal when prompted
4. Enter the playlist URL or ID:
   • Full URL: https://open.spotify.com/playlist/37hfuiahfibqiwbgfiuer
   • Just the ID: 37hfuiahfibqiwbgfiuer
5. The script will show playlist info and the number of new tracks
6. Confirm to add the tracks to your library

• The Spotify API allows adding up to 50 tracks per request
• The script automatically splits large playlists into chunks
• Already liked tracks are skipped
• For private playlists, you must be the owner or have access

• "Redirect URI mismatch" — Make sure the Spotify App has http://example.com/callback set as a redirect URI
• "Invalid client" — Check that your Client ID and Client Secret are correct
• "Insufficient client scope" — Delete the .cache file and re-authenticate
