Methods of electronic scheduling for playback of media contents are disclosed. Discrete items of content are scheduled for play back based upon a schedule created by the integration of scheduling methods into a single scheduling algorithm. In a first scheduling method, a discrete item of content is assigned a frequency rating relative to other items of content. A second way to schedule is repeating a content item at specific intervals of time. A third scheduling method allows the content to be played at a specific date and time. A fourth scheduling method includes playing a content item upon receipt of a trigger event which is received from a source external to the scheduling system. And lastly, means are provided for selectively determining whether or not particular content is available for play in a particular venue or during a particular period of time.
