The Playlists node contains all Playlists and AutoPlaylists that are part of your MediaMonkey Library. Playlists in this node can be organized hierarchically. You can Drag & Drop playlists onto another playlist to make it a child node. The parent playlist will not inherit the child playlist nodes files. AutoPlaylists can be configured to get files from other playlists. Deleting a parent playlist will also remove all its child playlists from the MediaMonkey Library.
Note that Playlists and AutoPlaylists are stored within the MediaMonkey database--if you wish to use these playlists within another application, you must export them.
See: Exporting Playlists
Playlists are simply collections of files arranged to play in a predefined order. When you add files to the Library, a playlist is created by default, showing all of the songs that have been imported at that time. If you've added playlist files from your PC through scanning into your MediaMonkey Library, these will automatically appear in the Playlists > Imported Playlists node in the Media Tree.
See: Using Playlists
AutoPlaylists are collections of songs that are created dynamically based on a chosen set of criteria. As new Tracks are added to the Library or changed, AutoPlaylists adjust dynamically so that any new Tracks that match the chosen criteria are added, and others that no longer match the criteria are removed.

Playing vs playlists
The Playing is a playlist used by the MediaMonkey Player. If you play a playlist Playing maintains no connection to that playlist. So any changes you make in the Playing are not saved back to the playlist and vice versa.
