Lee covered the bases well. Follow the link below to see what the 200 MHz. FM broadcast bandwith looks like. Don't forget that the signal moves as much as 100 KHz. to either side of the center frequency. The L-R signal is double side band (DSB) suppressed carrier. Beyond the upper sideband limit, is where a 67 KHz. subcarrier or hybrid digital HD is found. That 67 KHz. SCA has been used for "Muzak", among other things. Now you know why MPX decoder circuitry has a 67KHz. trap. ;>)
