Automated Playlist Generator

The Automated Playlist Generator (APG) automatically generates playlists based on constraints you set, these constraints can be set based on song data (Author, Artist, Genre) or acess time(Last Time Played), there are also special constraints to determine how Amarok is going to look for songs. You will find the APG in your Media pane, Playlists -> Automated Playlist Generator.

APG Presets' toolbar

This is the APG Presets' toolbar, from left to right we have the following buttons:

Add new preset: Adds a blank preset that can be modified.
Edit selected preset: Opens up the APG Preset Editor window to edit the currently selected preset's constraints.
Delete selected preset: Removes the selected preset from the list, can NOT be undone.
Import new preset: Import a preset from a .xml file, has the potential to be malformed if edited outside amarok, use the constraint tester.
Export the selected preset: Export the selected preset to a .xml file that can be imported.
Run constraint tester: Does nothing D:
Run APG with selected preset: Loads APG with the selected preset and automatically generates a playlist.

Presets

Presets are sets of rules that Amarok's APG will use when generating playlists, these rules are going to be refered to as constraints from now on, every preset is determined by the constraints that make it up, groups of constraints hierachically and logically organized are called constraint trees.

Constraints

Constraints are the building blocks of constraint trees, they are simple statements that the APG will use to add songs to the playlist it generates,

-You can create groups of constraints that you want to use often together, as in this example, for the Preset ''Example 1: new tracks added this week'':

+==Constraints==
-Notice that you can choose all or any of the constraints in the group.
-One can choose to constrain the playlist by:
-when the track was last played, whether or not artists, albums, composer, etc. should be repeated, total length of the playlist, score, year, labels, and many more. You can set multiple constraints, and choose how strictly each should be followed. For instance, if you want to burn a CD, you can choose one or a few genres, and set the length of the playlist as both approximately 75 minutes, and not longer than 80 minutes.
