Simple and hacky project that will automatically like all songs in all of the liked albums in your Spotify profile.
A couple things that will be needed. You will currently have to generate your own Shopify application at https://developer.spotify.com/
You will need a folder in your home directory named .spotify-song-liker with a file inside of this folder named application.properties
In this file you will initially need the following:
com.dwdking.spotify.credentials.clientId=<your generated client id>
com.dwdking.spotify.credentials.clientSecret=<your generated client secret>
The client id and client secret will be the values from your generated application registered at developer.spotify.com
Once this is done running ./gradlew bootRun will launch the app authorization page and allow you to authorize the app against your Spotify account.
Once it has been authorized an authorization code, access token, and refresh token will be stored to the application.properties file automatically.
You can then hit the endpoint http://localhost:8080/likeAllAlbumSongs, which will like all songs from all the albums you have already liked.
Goodluck!
