I haven't heard much Christian metal, but would say that I'm a fan of Demon Hunter. I've been given the names of other artists to listen to, but haven't yet. Just like any form/genre of music, it's a way to express yourself (and the band). For me, it's not about the type of music, but the message of the lyrics. To me, that's what is important: the meaning of the song, or what you take out of it.
