I don't know how you define Good country music, but AM is far from the only place to hear it. 
There was a time that I listened to music a lot. Tractor, combine, car, office, you name it. Classic country is my preferred genre. Kind of outgrew listening though, as sometimes quiet is good too. Tesla cars have a fabulous stereo speaker system but no radio of any sort. Their streaming service is second to none. And unlike Sirius or XM, there are no ads on the Tesla streaming service. You can pull up and play any genre. Skip over what's playing and go to the next selection by tapping the screen.
