This project is used to save the "Discover Weekly" playlist created by Spotify. The jar is executed by a cron job every week and stores the songs in a different playlist.
The app.config is the configuration file and must be located in the same folder as the jar.
If there is no app.config, the program will request all parameters.
In order to use the Spotify API, a client ID and a client secret are required.
These can be created here:
Spotify Developer Dashboard
ClientId From Developer Dashboard
ClientSecret From Developer Dashboard
PlaylistIdWeekly The Playlist ID from the Discover Weekly Playlist
PlaylistId The Playlist ID of the playlist in which the songs should be saved
