In one aspect, the method can include identifying a mobile audio player device that introduces a music selection to another mobile audio player device. A signal comprising the music selection, a musical identifier that identifies the music selection and an identifier that identifies the transmitting device is transmitted from a first mobile device to a second mobile device. The second device stores the musical identifier and the identifier of the transmitting device in association with one another. In another aspect, the devices are enabled to connect over a wide area network and use the identifiers to obtain the music selection from a music distributor over the network. In yet another aspect, the transmitting device receives points or other compensation for introducing the music selection to the second device. ## Claims ### Claim 1 A method comprising: providing a cluster comprising an original broadcast unit and at least one original receive unit wherein the original broadcast unit broadcasts media content to the at least one original receive unit;
