Jovi were popular here TD era?!! God, did I come to live here too late (well, born too late, too I suppose XD) Most everyone at my school really, really hate 'em. I'm a loner I tell ya!

As for the question, well, I don't think the guys' music is particularly religiously oriented in any way; God for sure is something mentioned repeatedly but I think it's for the sake of the theme, depending on the message that's supposed to be conveyed. Stuff with preachers and church and Hallelujah Amen is used in the religious context but not for Christianity in particular, ya know? But nothing to suggest that they're a Christian band or anything. They're not picky in the religious department.

For the record, I'm a Muslim and it don't affect the way I perceive or enjoy the music...in the end, you'd just think, why should I?
