“Gospel is about God; blues is about women”

the difference between gospel music and blues music is that “Gospel is about God; blues is about women.” The music saying has been cited in print since at least the 1970s and is of unknown authorship.
 
       
8 February 1970, The Sunday Star (Washington, DC), “The Rhythm, The Blues, The Roots” by Jerry Butler, Tuesday Magazine, pg. 10, col. 3:
It was also kind of off-limits, because to Mom and Dad there were only two kinds of music: good and bad. Good was the Gospel, which was talk about God and heaven. Bad was the blues, which talked about women and men and other worldly things that us kids should not know about.

Gospel and blues are almost the same. The difference is only that one is about God, the other one about women.

The only difference between Gospel and the Blues is, One’s about God, and the other’s about women.
