Click on a file in your library then click Enqueue...it will move down into the playlist pane. Add as many songs as you want this way, choose Shuffle or Continuous play, then double click a song to start playing!

You can save playlists if you like, but some people have run into problems with opening saved playlists after making changes. Have a look through the thread below for some more info:wink:
