Like it or not, Christian music is influenced by pop culture, to the point where it's often imitative rather than innovative. The best example of this is the new "Christian alternatives" to American Idol— Gifted.
Former American Idol stars Clay Aiken, George Huff, Mandisa Hundley all have been open about their faith, particularly now that they've moved on from Idol. For that matter, Carrie Underwood's star-making single after winning the competition was the prayerful, award-winning single "Jesus Take the Wheel."
I haven't seen this show, and I think it's actually over now for this season... but it is one that I would enjoy watching. I listen to a lot of Contemporary Christian music and would love to see if anyone from Gifted can make it big.
I'll do some more digging and see what I can come up with.
