How many alternative stations are occasionally playing music from Johnny Cash? The Edge in Phoenix has seemed to play a Cash song once a day for the past few months. I know the popularity of the movie "Walk the Line" was probably responsible for this phenomenon, but if they play Cash, why aren't they playing other "outlaw country" artists that have tried to appeal to listeners of alternative radio (Merle Haggard comes to mind)? Is it the same reason why some stations play Bob Marley, but no other reggae artists?
