A system, computer implemented method, and computer readable storage medium is provided which enables customers of an establishment to collaboratively reject a media file that is currently playing and/or pending to be played within that establishment by entering data into a personal wireless portable computing device on their person, for example a cellular telephone. Upon entering a rejection request, and where necessary an establishment identifier, a message is sent over a wireless link to a media server which performs a series of logical tests to determine if the media file is actually terminated prior to full completion of play. In this way, a plurality of separate customers may use their portable computing devices to collaboratively reject specific musical media file selections that are currently playing or currently pending for play within a particular physical establishment.
