I love this song so much. I picture Nina Simone singing this in the highly religious environment the USA is; and would have been even more so back then. It would have been so out of place, singing about heaven and hell based on how we live our lives:
If your mind lies in the devil's workshop and evil-doings your thrill... and trouble and mischief is all that you live for then you know damn well...
that you'll go to hell.
Oh and keep your children from doin wrong because you know damn well they'll go to hell.
And then just when we think it's a preachy song about doing right to stay in good with the lord we get:
Some say that hell is below us, but I say it's right by my side. I see evil in the morning, evil in the evening and you know damn well... that we all must be in hell.
We all sin, none of us are perfect... we all must be in hell? Let's make sure we all enjoy it here.
