Cover art for Sway lyrics by Coal Chamber

I think it's about someone that always does something to a guy, and it drives them insane.

"It just sits inside so it burns and burns If I can't decide what makes you hurt"

He's letting all his anger bottle up inside of him. Then, he literally sets the guys house on fire cuz he's sick and tired of being picked on or whatever, and he's watching the flames sway in the wind, and he's fixated by them. Probably wrong, but whatever.
