I remember the theme, never knew it had words. I just listened to the link you shared, and after about a minute had to nope right out of there.
Seriously the hair on the back of my neck stood up... just creepy.
If you haven’t seen the original movie the theme song, sarcastic as it was, is used during the fake suicide scene for Painless (a Dentist).
***spoilers***
Painless apparently swings Big Meat. He had an event where he couldn’t get it up and wanted to kill himself. The docs addressed his depression and his desire for a “living funeral” where he would ultimately take the Black Pill. It was a knock-out pill (not a real black pill) and he woke up to the ministrations of a nurse. Who cured his depression.
