Individual audio replay devices are coupled to a source device for downloading selected playlist information items, for updating a local playlist in the individual audio replay device. The updated local playlist is used to control selection and a sequence of play of tracks by the individual audio replay device. Preferably, the playlist information item indicates the sequential position of the track in the system wide playlist and the local playlist by means of a sequence number for the track in the playlist, the sequence numbers of the playlist information items being set in the defining step so that space is left for later definition of playlist information items with sequence numbers that correspond to insertion among tracks in a previously defined playlist. Preferably at least one of the playlist information items contains playlist specific virtual editing information, for editing the track that is associated with the at least one of the playlist information items according to the virtual editing information and replaying the edited track when the playlist is replayed in a device.
