1. A method of promoting user participation in a social broadcast environment, comprising: determining, based on an attribution criterion, that one or more users are to receive credit for: 1) designating a track currently being played on air during a radio broadcast; 2) interrupting the track currently being played on air during the radio broadcast; and 3) causing the track to be taken off the radio broadcast immediately by a group action applied to the currently playing track, wherein the group action is input representing the preferences of the users in the group; generating, by a processor, an audio signature of the group by processing group profile information, wherein the audio signature is speech synthesized from the group profile information; and including in the radio broadcast, by the processor, immediately after the track is taken off the radio, an attribution content comprising the generated audio signature associated with the group.
