Casting Crowns, The Afters and Tenth Avenue North currently top the list.
I've got nothing against Christian music at all. My issue is with the idea that's seemingly been implied in this thread, and outright stated other places I've seen, that music must explicitly mention God/Jesus in order to be Christian. Maybe an example will illustrate a bit where I'm comming from.
Are these lyrics "Christian"?

It's a song written and performed in the early 80's I beleive, but Peter Gabriel, a decidedly non-Christian artist. If not then did it suddenly become Christian when it was re-recorded by Nichole Nordeman and played on KLOVE?
In my opinion ANY music that causes the listener to turn their heart/mind toward God is christian. The point of view or intent of the author/performer is largely irrelevant. And music from an artist who is a Christian, but who chooses not tbe be specifically known as a Christian artist is no less Christian than music from an artist signed on a Christian label and only played on Christian radio. The "ah ha" moment when pointing out the Christian meaning in a song by the Fray, or Switchfoot to someone who had never noticed it before is very powerful in evangelizing.
