\subsection{Playlist terminology}
Some common terms that are used in Rockbox when referring to
playlists:

\begin{description}
\item[Directory.] A playlist! One of the keys to getting the most out of
  Rockbox is understanding that Rockbox \emph{always} considers the song that
  it is playing to be part of a playlist, and in some situations, Rockbox will
  create a playlist automatically. For example, if you are playing the
  contents of a directory, Rockbox will automatically create a playlist
  containing the songs in that directory. This means that just about anything
  that is described in this chapter with respect to playlists also applies to
  directories.

\item[Dynamic playlist.]  A dynamic playlist is a playlist that is created
  ``On the fly.'' Any time you insert or queue tracks using the
  \setting{Playlist submenu} (see \reference{playlist_submenu}), you are
  creating (or adding to) a dynamic playlist.

\item[Insert.] In Rockbox, to \setting{Insert} an item into a playlist means
  putting an item into a playlist and leaving it there, even after it is
  played. As you will see later in this chapter, Rockbox can \setting{Insert}
  into a playlist in several places.

\item[Queue.] In Rockbox, to \setting{Queue} a song means to put the song
  into a playlist and then to remove the song from the playlist once it has
  been played. The only difference between \setting{Insert} and
  \setting{Queue} is that the \setting{Queue} option removes the song from the
  playlist once it has been played, and the \setting{Insert} option does not.
\end{description}

\subsection{Creating playlists}

Rockbox can create playlists in four different ways.

\subsubsection{By playing a song}
Whenever a song is selected from the \setting{File Browser} using the
\opt{IRIVER_H100_PAD,IRIVER_H300_PAD}{\ButtonSelect} button, Rockbox will
automatically create a playlist containing all of the songs in the directory
in which that song is located.

\note{If you already have already created a dynamic playlist, playing a new
  song will \emph{erase} the current playlist and create a new one. If you
  want to add a song to the current playlist rather than erasing the current
  playlist, see the section below on ``Adding music to playlists.''}

\subsubsection{By using Insert and Queue functions}

\subsubsection{By using the Playlist Catalog}

\subsubsection{By using the Main Menu}

\subsection{Adding music to playlists}
  
\subsubsection{\label{ref:Playlistsubmenu}Adding music to a dynamic playlist}
\screenshot{rockbox_interface/images/ss-playlist-menu}{The Playlist Submenu}{}
The \setting{Playlist Submenu} allows you to put tracks into a
``dynamic playlist''. If there is no music currently playing, Rockbox will
create a new dynamic playlist and put the selected track(s) into the
playlist. If there is music currently playing, Rockbox will put the
selected track(s) into the current playlist. The place in which the newly
selected tracks are added to the playlist is determined by the following
options:

\begin{description} 
\item [Insert.] Add track(s) to playlist. If no other tracks have been
  inserted then the selected track will be added immediately after current
  playing track, otherwise they will be added to end of insertion list.
  
\item [Insert next.] Add track(s) immediately after current playing
  track, no matter what else has been inserted.
  
\item [Insert last.] Add track(s) to end of playlist.
  
\item [Queue.] Queue is the same as Insert except queued tracks are
  deleted immediately from the playlist after they've been played. Also,
  queued tracks are not saved to the playlist file (see
  \reference{ref:playlistoptions}).
  
\item [Queue next.] Queue track(s) immediately after current playing track.
  
\item [Queue last.] Queue track(s) at end of playlist.
\end{description}

The \setting{Playlist Submenu}  can be used to add either single tracks or
entire directories to a playlist. If the \setting{Playlist Submenu} is
invoked on a single track, it will put only that track into the playlist.
On the other hand, if the \setting{Playlist Submenu} is invoked on a
directory, Rockbox adds all of the tracks in that directory to the
playlist.

Dynamic playlists are saved so resume will restore them exactly as they
were before shutdown.

\subsection{Saving playlists}
To save the current playlist either enter the \setting{Playlist} submenu
in the \setting{WPS Context Menu} (see \reference{sec:contextmenu}) and
select \setting{Save Current Playlist} or enter the
\setting{Playlist Options} menu in the \setting{Main Menu} and select
\setting{Save Current Playlist}.
Either method will bring you to the \setting{Virtual Keyboard} (see
\reference{sec:virtual_keyboard}), enter a filename for your playlist and
accept it and you're done.

\subsection{Helpful Hints}

\subsubsection{Including subdirectories in playlists}
You can control whether or not Rockbox includes the contents of
subdirectories when adding an entire directory to a playlists.
Set the \setting{Main Menu $\rightarrow$ Playlist Options $\rightarrow$
  Recusively Insert Directories} setting to \setting{Yes} if you would like
Rockbox to include tracks in subdirectories as well as tracks in the
currently selected directory.
