+If you would like to import all your previous last.fm scrobbles, use [benfoxall's website](https://benjaminbenben.com/lastfm-to-csv/) ([GitHub page](https://github.com/benfoxall/lastfm-to-csv)). Use the python script lastfmconverter.py with two arguments - the downloaded csv file and your new tsv file - to convert your data. Place the tsv file in logs/ and the server will recognize it on startup.
