These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way.

YMMV: Mr Bungle
Creator's Pet: Was accused of this by several of Patton's fans, especially in the early days. Despite all the success of his new band Faith No More in the late 80s, Patton seemed more focused on getting exposure for Bungle and fought to get them signed to Warner. Was part of the early friction with FNM.
Ear Worm - Now I'm findiiiiiing truuuuuuuth is a ruin...
Hell Is That Noise - The aforementioned endings of "The Bends" and "Goodbye Sober Day," as well as the ending of "My Ass Is On Fire."
The end of Egg can qualify too, as the band performs one of the most accurate pastiches of Captain Beefheart ever put to record, which can be disturbing to some in a musical Uncanny Valley type way
Magnum Opus - Often considered to be Disco Volante, although all three albums have substantial contingents of fans who will vouch for them.
Nightmare Fuel - "Everyone I Went To High School With Is Dead" is about a murderer who is killing his old high school schoolmates and using the yearbook as a way to track the ones that he already killed. The music itself is chaotic and distorted, with random, agonized gibberish thrown in for good measure.
can also be seen as an example of Lyrical Dissonance if you take the alternate interpretation of the lyrics, which makes them just existential musings on mortality
Honestly, half of their catalog could be considered "Nightmarish".
Nightmare Retardant: The hidden track at the end of Disco Volante initially comes off as Nightmare Fuel; it's distorted and ominous, and its supposed title - "Nothing" - recalls Nihilism. Then you realize it was a case of Throw It In, the title an in-joke.
