Systems, methods, and computer-readable storage media for dynamic radio content. The system generates a media item to be inserted into a media stream. The media item can include multiple segments associated with a set of discrete components. Next, the system inserts the media item into the media stream. In response to a triggering event, the system then re-generates the media item by assembling the multiple segments using a new set of the discrete components. The system then inserts the re-generated media item into the media stream.
