I agree with vrt. I'm an atheist, but love listening to Christian bands that have a subtle message. My favorite christian band is Skillet, and I even like their very 'God-loving' songs, mostly because I don't really care if there is a god or not (guess that makes me more of a agnostic maybe? but i personally don't believe in god, so i'd say i'm more of an atheist). I hate listening to gospel, or any music that forces god on you, just the same as i hate talking to people who force their religion on you, whether it's islam, christianity, judaism, atheism, whatever.
Personally, I listen to music because I like the music, lyrics, and/or message. I have a very wide breadth of genres I listen to, and there is very little I really dislike. Unfortunately, most of the mainstream can bear no more than Jars of Clay-like bands, whose messages in their mainstream music is almost non-existant, which I actually don't mind...just give me good music, ok?
