Magnificent Bastard/Music

Doctor Steel has loyal followers proclaiming devotion all along the globe, all simply because of catchy music. Is this real? Or is he just stringing us all along? Who knows? Who cares? Magnificent, indeed.
The Offspring's song You're Gonna Go Far, Kid: "Show me how to lie; you're getting better all the time, and turning all against one is an art that's hard to teach. Another clever word sets off an unsuspecting herd, and as you step back in line a mob jumps to their feet. Now dance, fucker, dance. Man, he never had a chance, and no one even knew it was really only you." If that's not this trope in lyrical form, I don't know what is.
Lord Donald in the Fairport Convention song "Matty Groves", upon finding his wife cheating on him, insists on allowing her lover to get dressed and even gives him a sword to fight him with. He kills the lover and his wife, but insists that she be buried on top because "she was of noble kin."
