I found a couple old MP3s on my computer which were supposedly by Slipknot, but they don't really sound like them. They're called People = Shit and The Heretic Anthem, and I thought they were actual Slipknot songs until I got Iowa a few years ago and heard completely different songs by those names.
It's sort of hard to describe them. They had guitars and screaming, but also rapping and synths and stuff. Lyrics include lines like "I feel the pain...SOOO CONFUSED!" and "SUICIDE!" and stuff. They're sort of hard to understand, but I can piece together words here and there. "YOU'RE KILLING MY TRUST-"... something.
Does this sound familiar to anyone?
