spotifySyncer

Sync Spotify Playlists with each other and keeping the order
this library is a wrapper for spotipy

Requirements

sudo apt install libcairo2-dev libgirepository1.0-dev
pip install argparse spotipy pandas

Create Spotify Developer App

To start using this code you must first create an app in spotify developer
set App name and description as you want and set Redirect URI to https://www.example.com
after creating your app head on to your app settings and copy the Client ID and Client Secret and your done with this dashboard

Copy Playlists Id

then go to your Spotify account and copy the share link for the playlists you want to sync (for liked-songs playlist just put saved_tracks)
Note: share links will look something like https://open.spotify.com/playlist/{id}?si={something} and we only want the id part

Authentication

this script uses spotipy Oauth so the first time you run the code it will open a browser and ask for verification
after accepting the agreement you will be redirected to another page (https://www.example.com)
then you must copy the full link (with parameters) of that page and paste it into the terminal to complete the verification

CronJob

you can add this script as a CronJob to be updated at a desired timespan
you can also use --sync_every option to make sure if the script ran multiple times, the additional sync requests will be filtered out
example cronjob to run every hour but sync every day:
0 * * * * XDG_RUNTIME_DIR=/run/user/$(id -u) /path/to/spotifySyncer.py saved_tracks PLAYLIST_ID -id CLIENT_ID -secret CLIENT_SECRET -se 86400

Why do it like this?

this is done to make sure the playlist will be updated if the system is up for an hour but also avoids additional bandwidth and system usage
for example, if the first try fails due to the systems internet connection it will be synced at the second try the next hour but it will not be synced until 24 hours after the successful sync
the XDG_RUNTIME_DIR variable is used to keep the notifications working
