Other than John Lennon's "Imagine," is there another atheist/agnostic song.
The only one I can think of is "Dear God" by XTC.
Tim Minchin, Shelly Segal be Roy Zimmerman are a few atheist singers who specialize in the genre. There are thousands of atheist songs, and there will be more as the up and coming more secular youth grow up.
With that said though "imagine" is my all time favorite.
A song that comes to mind is "What If God Was One Of Us" by Joan Osborne.
I like that song a lot, but I can't remember enough of the lyrics. I'll have to add it to the end when I look at all these songs I don't know. This has been a very educational experience.
Explicitly or inferred, or secular? So many songs could fit. Or anti-theist, even.
I'm not picky. I am learning quite a bit. I like inferred. Sneaky is good.
That frees up many options @phil21
I could post lots and lots of death metal songs that are unequivocally atheistic. I'll limit myself to mentioning just on example, that being "The Greatest of All Lies" by Unleased.
