Systems and methods for creating one or more playlists of a predefined length. The invention allows dynamic creation of different playlists for differing times, locations, and other circumstances and also provides for the dynamic selection of products for inclusion in a playlist based on the content of one or more of the individual products. Creation of a playlist may be based on a priority scheme with priority values indicating the relative importance of the products. Creation may also involve determining or adjusting the lengths of one or more products selected for the playlist so that the total length of the playlist will equal a set, predetermined, or otherwise predefined playlist length. Methods and systems according to the present invention provide flexible, efficient, and manageable techniques for creating different playlists of similar product types for both varying circumstances (e.g., time, location, etc.) and varying products of those product types (e.g., clear radar versus radar showing movement of a complex storm system). The invention gives an administrator the ability to simply and easily manage the broadcasting of different playlists for different conditions.
