An enhanced media item playlist on which a media item identifier for a media item and presence information of a recommender of the media item, and, optionally, a media item annotation from a media item recommendation message, may be stored is disclosed. The playlist may be any accessible and/or manageable format, for example a database, for storing or containing the media item identifier, the presence information, the media item annotation, and/or the media item. The presence information and, if present, the media item annotation are stored on the playlist in a manner associated with the media item identifier. In this manner, the recipient of the media item recommendation message may store, manage, and access the presence information and, if present, the media item annotation, and not only render and/or transfer the media item recommended, but also the presence information and the media item annotation.
