Definitely unreleased because you hear it in the background on the kiss skit, this song existed in some form since then. Now could he have used some AI to clean it up? Sure but it doesn't sound like it.
Anti-christ was an older track too but he re-wrote it and made it 10x better with newer references. This song is a time capsule which is why nikkas seem like they having fun with it for the most part lol
Crazy shyt is, swap this, and Stimulate out for a couple of the skips on The Eminem show (drips, my dads gone crazy) and the shyt is flawless.
