Christians already have hundreds of years worth of some of the best music ever written. If the Lutheran church still played Bach Cantatas during the service, I might go every day (and I am thoroughly unreligious). Then there's all the gospel music that's more modern. I understand it's not the same thing as pop culture and it's a hard sell for those trying to be cool, but it has to be a better strategy than miserably imitating decidedly un-christian pop culture.
