The automated switching of broadcast sources of an audio content stream based on the geographic location of the physical unit that is receiving the audio content stream. For instance, while rendering a particular audio content stream from a first broadcasting source, a system may have an identity of one or more alternative possible broadcasting sources available for the same audio content stream for that relative geographic location. In response to some decision making, the system may decide to switch broadest sources for that audio content stream. Thus, the user continues to listen to the audio content stream without being subject to possible negative consequences of continuing to listen to the audio content stream as received from the original broadcast station. Data transmitted by the broadcast stations themselves need not be relied upon. Thus, the automated switching is accomplished even outside of regions in which broadcast stations transmit such data.
