Who can outdo me for songs about even more despicable characters ? : ) More points if it's your own original !!! :0
Yeah...I'm not playing. I've heard WAY too many songs that make you want to un-listen to them. I'm not sure anyone would go looking them up for one; and I wouldn't want anyone looking them up for reason number two.

A quick example would be something like "Dead Skin Mask" by Slayer. It's about Ed Gein. The unsettling part is it's from Ed Gein's perspective! No thanks.
If you go into the death/dark metal genre of music, it gets weird quick. A lot about rape, molestation, murder, torture, aborted fetuses...even necrophilia, if that puts it into perspective. That's why I'm not playing. None of us needs the therapy bill that would result from playing this "off topic" game. lol
I'm actually finding this whole "Baby Shark" song to be rather evil.

I actually came here to answer this...
I forget the name of this song, but the chorus goes -
"I swear I left her by the river,
I swear I left her safe and sound
(I forget the next bit)
And leave this cold Nebraska town"
I believe that's "Hazard" from Richard Marx. He actually has many songs much better than that one IMO.
