A dynamic playlist is a playlist that is based on a filter. For example, this can be "5 star" tracks, live recordings, tracks produced by a specific producer, tracks where a specific musician appears, or tracks you have not played the last 3 months. You can filter on any data field in the album and track tables. The playlist can also be randomized. The contents of a dynamic playlist is automatically updated as you add, edit and delete information in the database.

Two of the data fields are of special interest when setting up a dynamic playlist: Max Tracks and Random. In the Max Tracks field you define the maximum number of tracks the playlist can contain. If you check the Random field, CATraxx will pick the tracks at random when opening the playlist.

For example, suppose you have set up a filter that returns 1000 tracks. If you set Max Tracks to "50" and check the Random field, CATraxx will pick 50 of the 1000 tracks at random each time you open the playlist.

If you do not check the Random field, CATraxx will always pick the first 50 tracks according to the defined sort order.
