I don't mean songs that have been used for evil purposes, or which have evil connotations now. Dixie's lyrics aren't exactly wicked. Nor, curiously enough, are Deutschlandlied's.
And I think for the moment I'll classify those that go out of their way to praise evil as "explicitly evil." I'd lump the "I'm so bad" rap songs in here too.
I'm wondering now about the "seductively evil;" songs that seem innocent but aren't.
"Imagine" is pretty obviously a wicked song, cloaked in apparent kindness. Another that jumps to mind is "Gentle on my Mind:" abandoning the lady and expecting her to wait for you is made to seem so natural. "Different drum" has always seemed to corrode the possibility of any relationships--not just romantic.
My impression is that there are a lot of songs designed to aid in seduction; playing up the urgency of the moment and playing down conscience. And I hear of (but don't make a habit of listening to) a number of nihilist songs, many of which seem to be not-so-seductive cries of pain.
I'm not sure searching out and ranking "seductively evil" songs would be good for the soul. But maybe recognizing them is a good way to resist them. What you immerse yourself in effects you.
