$ docker run -v "$(pwd):/music" --rm spotdl/spotify-downloader sync https://open.spotify.com/playlist/3zm1edwUQr94IznMv2PXiv?si=b342fc800a14433e --save-file life-is-strange.spotdl

Subsquent runs

Download spotdl-sync.sh spotdl-sync.service spotdl-sync.timer to the directories as mentioned in the beginning of each script. Update the download directory in spotdl-sync.service from /media/spotdlsync to whatever you kept in the first run section above.

Then run these:

$ sudo chmod +x /usr/local/bin/spotdl-sync
