I don't mind the "secular" Christmas songs, but do prefer the religious Christmas songs. Even so, how many times can you listen to Oh Holy Night or Silent Night between now and Christmas.
On the other hand, generally speaking, almost all Christmas Music has a happy message (there are some that are sad like Blue Christmas and I'll Be Home for Christmas, etc) and in these days of serious economic problems facing the nation and world maybe folks find some escape through this happy form of music. So in that sense, it might be a good thing for those who chose to indulge so early before Christmas. Maybe for a short time, the music takes their minds off their troubles.
In any case, apparently enough of the right type of listeners want Christmas Music this early or stations like WJBR wouldn't bother.
