Abstract: The present invention is directed to systems and methods for recording, storing and playing back audio and video works. In one embodiment, a method of presenting a variable work, such as an audio track, to a user includes presenting a first version of the work to the user. The first version has a trigger point therein. The method includes presenting a second version of the work to the user if the first version trigger point is reached during the presentation of the first version. If the first version trigger point is not reached, the first version is re-presented. In this manner, the use of a trigger point within the work can help determine whether the user should be presented with the same work again, or a different version of the work, upon subsequent views or listenings of the work.
