I definitely think more atheistic, or agnostic based songs need to be written.
I was raised in a Christian family and taught from a young age to believe in, and fear God, Jesus, Satan and the rest. I recall a time when I was about 8 years old when I began to question it all. I would ask my mother, gandmother, or even raise my hand in Sunday School (when we were learning about one or another of the biblical parables) and ask questions to the effect "But, how could....?" Well, my questions were most often politely brushed off, but sometimes coldly stomped on. Either way I never really had them answered.
For a few years I remember feeling quite a sense of alienation with respect to my religious doubts. I new things didn't add up, but I had no good way to articulate what I was thinking and feeling. I thought maybe I was the only one.
Then when I was 11 years old I had a seminal moment which I still remember to this day. Our school bus driver would play the local rock station on the drive home. A song came on the radio who's lyrics helped me towards a path of putting my thoughts in focus. It was Rush's Freewill.

This song had a huge impact on me and made me feel like I wasn't alone. And isn't that one of the most wonderful things that music can do?
Admittedly, Freewill is as much a criticism of religion as it is a guidepost to an alternative way of thinking. But, having been raised in religion it was just what I needed at the time. I would love to hear more songs of this kind. Especially ones who's voices are less reactionary and just simply speak positively and beautifully about discovering the mysteries of the universe.
I know atheistic, agnostic, existential (or what ever you want to label them) songs could potentially be as grand and moving as any religious song every written. If you don't believe me, check out this poem. It speaks for itself.
[size=small]life is more true than reason will deceive
(more secret or than madness did reveal)
deeper is life than loss: higher than have
--but beauty is more each than living's all
multiplied with infinity sans if
the mightiest meditations of mankind
canceled are by one merely opening leaf
(beyond whose nearness there is no beyond)
or does some littler bird than eyes can learn
look up to silence and completely sing?
futures are obsolete; pasts are unborn
(here less than nothing's more than everything)
death, as men call him, ends what they call men
--but beauty is more now than dying's when
