"You probably don't listen to any of those New Christian Contemporary Christian stations "
I don't either. The music is of such low quality that it's unbearable. The radio demographic is the 30-something soccer Mom, and they must like that stuff.
Some of the bands which aren't on the radio are much better.
One of the big attractions of these stations for the demographic of which you speak, and which I fit into very well, is that you can listen to it with the kids in the car. The lyrics are clean and about God and the talk in between the songs isn't about all the trash that permeates the airwaves these days.
So yes, I listen to Christian radio because it is the cleanest and most wholesome thing I can let my kids listen to. It may not be the greatest, according to music snobs, and the playlists are usually pretty small so you tend to get alot of repetition, but it's no worse than the dreck you'd hear on Top 40 without all the sex and smut talk along with it!
