## Non-existence Songs
If a move action or a remove action as defined in the **actions file** attempts to move or remove a song which does not exist in the playlist, your program should ignore such an action.
<!-- ### Command 1: add a music track to a playlist
The first argument is the name of an input file which contains a playlist - in this README, we will refer to this file as the **playlist file**. The second argument is the name of another input file which contains all available music tracks - in this README, we will refer to this file as the **library file**. The third argument is the output file. The fourth argument is the action, which in this case is "add". The fifth argument is the title of the music track.
