Every time you like a song, it gets added to a playlist called "Inbox", which holds all the songs you want to eventually add to your other playlists. You should clear your inbox on a regular cadence. This involves removing songs from the inbox and adding them to your other playlists (e.g. "Party Bangers").

This Trigger fires every time you save a new track to Your Music on Spotify.

This Action will add a track to a playlist given a TrackID
