1. A method comprising:
at a cloud-based connected radio service associated with broadcast radio stations:
receiving cellular network information and broadcast radio audio stream information from multiple client radios over wireless data connections with the multiple client radios;
upon determining that the multiple client radios are all simultaneously accessing a same unicast audio stream associated with a particular broadcast radio station among the broadcast radio stations over a same cellular network based on the cellular network information and the broadcast radio audio stream information, configuring the same cellular network to convert a designated audio stream associated with the particular broadcast radio station to a multicast audio stream; and
upon receiving a multicast address for the multicast audio stream from the same cellular network, sending the multicast address to the multiple client radios over the wireless data connections to enable the multiple client radios to access the multicast audio stream.
