# Add tracks to a Spotify playlist

Automatically add tracks to a Spotify playlist on open.spotify.com. Add one or more tracks to the end of a playlist the signed-in Spotify account can edit, in the order given. Spotify accepts duplicates, so a track already in the playlist is added again. Returns the playlist's track count before and after, so the addition can be checked. Use remove_tracks_from_playlist to undo it.
