Playlists are ordered lists, and are used when you want to preserve the order of tracks. For example, you may create a playlist for "Top 40 1971" that preserves the order of the tracks. You may also want to create a compilation playlist of your favorite tracks, in order of preference. You can also create a playlist with your favorite Radio Stations, so that they are easily accessible at all times.
The point of creating Playlists is to group your collection in groups that you identify, and which are then very easy to access.
Playlists are accessible in the organization tree.
