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.
Harsher in Hindsight: "Killing an Arab". They don't perform it anymore, unsurprisingly (or when they do, they change the lyrics around heavily; some of the alterations include "Killing Another", and more humorously, "Kissing an Arab").
Magnum Opus: The 1989 album Disintegration bridges the gap between their Goth Rock work and their pop work, and its large number of classic songs has made it so.
Other often named contenders for this trope, are Pornography, an incredibly dark, and influential release that was the culmination of the goth sound that the band adopted in 1980, or the sprawling Kiss Me Kiss Me Kiss Me, an album that features the band explore numerous different styles.
Misaimed Fandom: Enough of it for "Killing An Arab" that they had to put a sticker on Staring at the Sea to decry racist use of the song.
Word of God says that it is about scary stories his father told him just before bed, which freaked him out.
Pornography. This is their darkest album, and it sure sounds like it. Definitely not a good idea to sleep to this.
In fact, the album opens up with the lines "It doesn't matter if we all die". Touching.
It gets worse. The last track, "Pornography", is filled with dissonant guitars, gloomy synths, backward snippets of unknown clips, and Smith's depressing vocals, probably making it the band's darkest and scariest song. If you do sleep to it, you're more than likely to get jolted awake by the ear-splitting feedback at the very end.
Replacement Scrappy: Arguably Jason Cooper. Even recently some fans of the band were still calling him a terrible drummer just because he replaced fan-favorite Boris Williams, despite the fact that by that time Cooper was longer in the band than any other drummer (Williams, Andy Anderson and Lol Tolhurst).
