Religious music for less than devout

One word for Christian music - Skillet! 

It may be mentioned here, I haven’t read the whole thing, but Jonathan Schlitt of Head East went to Petra and John Elephante of Kansas went solo Christian, It is good music.
DC Talk had a couple of songs hit the top 40 Charts.... I’m thinking of "Flood".... Jars of Clay had a couple get in there. PFR & Audio Adrenaline rocked quite well.
Jon Anderson from Yes, did a song with 4 Him called "The Only Thing I Need"   Also, Mumford & Sons has alot of Christian overtones. 
There is actually a fair amount of Christian music that is good music regardless of the emotional connection.

There is also Pie Jesu done by many  and written by Andrew Lloyd Webber at the loss of his father, sung well by Anna Netrebko on her Souvenir album and by Sissel. Both can be heard on u-tube. A gorgeous song. 
O Magnum Mysterium written by Morton Lauridsen is also beautiful. It can be found on Lauridsen’s CD Lux Aeterna on the RCM label and also it is done by Robert Shaw on the CD named O Magnum Mysterium on Telarc.
Again, anything Bach. To Bach,” The aim and final end of all music should be none other than the glory of God and the refreshment of the soul.”
I would self-label as devout, but, like n80, I really don’t like popular Christian music, though the old hymns still stir the heart.

For irreverence, "God May Forgive You (But I Won't)", written by Harlan Howard & Bobby Braddock. I have it in recordings by both Iris Dement and Rosie Flores, both great.

I love Lee Ann Womack's music, and many of her songs are Christian oriented.
I particularly like All His Saints, and her collaboration with The Fairfield Four - Children Go Where I Send Thee
