Well, if you look into the backgrounds of a lot of the old bluesmen from the early part of the twentieth century, you find out they were deeply religious people. That's what the Blues were all about, people struggling to "be good" instead of drinking whisky and sleeping around. So I think the Blues is the best music with religious influence. And the Blues was a direct influence on basically all modern music.
Overall, though, I think there is much more good secular music than there is religious music. Virtually all of the good rock artists are blatantly secular or even anti-Christian, even though in most cases they were influenced by the Blues. There were also some Blues artists who were against the Christian society they were raised in, such as John Lee Hooker. Then there's that whole deal with the devil myth about Robert Johnson, and indeed, he has several songs about walking with the devil. The rest of his songs are about drinkin' and screwin', and he was an influence on everyone who picked up a guitar since, from Eric Clapton to Keith Richards to Dave Matthews to John Mayer.
Like I said in the other thread, though, good music is good music. No religious musician has ever come close to the guitar virtuosity of Jimmy Page or the poetry of the Doors, both of which are clearly anti-Christian. Although, if you count Santana as religious, he comes close to Page :)
As for mosh pits, I mostly don't like them. One time I lost my glasses in one and another time I lost a sneaker and had to walk home in the snow.
