Spotify Discover Weekly Retention

Automatically saves tracks from your Spotify Discover Weekly playlist into a permanent playlist, so you never lose them when it resets each Monday.

Prerequisites

• Java 26
• A Spotify Developer app with the following redirect URI: http://127.0.0.1:8080/login/oauth2/code/spotify

Setup

1. Clone the repo
2. Copy .env.example to .env and fill in your Spotify credentials
3. Add the env vars to your run configuration (see .env.example)

Configuration

The app reads the following environment variables (wired through application.properties):

Variable	Description
SPOTIFY_CLIENT_ID	Client ID from your Spotify Developer app.
SPOTIFY_CLIENT_SECRET	Client secret from your Spotify Developer app.
TARGET_PLAYLIST_ID	The Spotify playlist ID to copy Discover Weekly tracks into. Must be a playlist you own.

The Discover Weekly playlist itself is discovered automatically from the authenticated user's library — no ID is required.

Spotify scopes

The OAuth flow requests the following scopes:

• playlist-read-private
• playlist-modify-private
• playlist-modify-public
• user-library-read

Running

./mvnw spring-boot:run

Then visit http://127.0.0.1:8080.
