To generate unofficial artist data, make sure the librespot server is running by running the following command:

java -jar ./core/target/librespot-core-jar-with-dependencies.jar <spotify_username> <spotify_password>

This command is explained here.

Next, create an artists-list.csv file and fill it with information, as detailed here. A sample file is provided just in case, as artists-list-example.csv. Simply rename the file if you’re just testing out the functionality.

Next, enter the Unofficial folder and run ./generate-unofficial-data.py. An artist list named artists-list.csv is required in the top-level directory.

Finally, wait for the data to be generated. It should take around 15-20 minutes if your list is particularly large, as we add sleeps on every iteration to protect you from getting rate-limited.
