As a popular music historian (of a sort), I am constantly banging head first into hit songs about people's imaginary friends. And, as such, I mourn for the nation and the world.
Question 1). Which are your most hated god-centric popular songs? (Mine are, in order, "God Bless The U.S.A." (Lee Greenwood), "Jesus Take The Wheel" (Carrie Underwood) and "Jesus Walks" (Kanye West).
Question 2). Do you have any god-centric popular songs that you rather like, despite their theme? (I'll only admit to "Spirit In The Sky" by Norman Greenbaum, though there are one or two others.)
Question 3). This one is going to be a stumper, I fear. Aside from "Imagine" by John Lennon, is there/are there another/other popular song(s) which are expressly atheistic/humanistic and specifically don't call upon an invisible friend? (I say "popular," in that there are probably many by a variety of indie artists, but those don't necessarily swim in the mainstream where everyone would have heard it on the radio.)
There are a million reasons why there wouldn't be -- not the least of which it's hard to sing about a negative of something (belief), but maybe I'm overlooking something.
