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. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
The choking sounds heard in the song "Force Fed Broken Glass"
Misattributed Song: Cannibal Corpse never did a song with GWAR called "We Are Your Enemy"; the song was done by Dying Fetus, and Dying Fetus alone. And "Damnation" is by Morbid Angel, not Cannibal Corpse. The latter mistake occurs much less, mostly due to Morbid Angel being the most famous death metal band aside from Cannibal Corpse themselves.
Narm: Sometimes their lyrics get a bit too over-the-top. Narm Charm is definitely there, but YMMV.
NIGHTMARE FUEL: There is a reason why the trope name is written in bold, italics and with all caps. Several of their songs could qualify, but the best contender(s) would be the album art.
