The radio is actually powered by the electrical system and can draw current from the battery. There is no mechanical linkage between the engine and the radio.
But seriously, yes - BMW has what is called "radio ready mode". If you have CA, this mode is attained by pressing the Start/Stop button a single time without your foot on the brake - this turns on the electrical system, including but not limited to: radio, homelink, sunroof controls, iDrive system, bluetooth pairing, etc.
If you shut off the engine with a single push of the start/stop button, you stop the engine, but return to "radio ready mode". A second push will turn off the electrical system. Opening the driver's door will also shut down the system.
