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 self-titled debut deserves special mention, as it was the beginning of the Nu Metal era in earnest. It cannot be overstated just how fresh the album sounded at the time.
For both Korn and Pink Floyd, whenever the former plays their cover of "Another Brick In The Wall" live, expect everyone present, many of whom are more likely to have been too young to remember the latter in their heyday, singing, with the strength of every fiber of their being, "HEY! TEACHER! Leave those kids alone!!" It really proves that song's staying power.
Base Breaker: See You On The Other Side alienated some of the more "hardcore" Korn fans with its softer sound. The Untitled album was supposed to bring back the fanbase, but it didn't help much...
This continued to occur for their single Never Never, and many fans wondered if the new album would be any good. However, the new album seems to have received praise from many fans for returning to their Nu Metal roots.
The return of Head has helped immensely.
Speaking of which, his departure from Korn in 2005 caused quite a stir among fans. Not just because of the departure itself but also because of the reasoning behind it (his conversion to Christianity). A matter not helped by the fact that, for a short while afterwards, he was publicly denouncing the band (especially Jonathan Davis) and its music. While he remains a dedicated Christian to this day, his views of the band and its music have softened up considerably.
Tear Jerker: "Daddy". The singer himself starts crying. The entire song is about child abuse. He comes close to it again in "Kill You", about his step mom.
He also cries a little bit at the end of "Holding All These Lies." Of course, considering that Remember Who You Are was all about returning to form, one can't help but question if this bit of crying was genuine or done for the sake of nostalgia.
Pretty sure the crying in "Holding All These Lies" is genuine. An interview by Revolver reveals this is the first time Jon has cried during recording since Life is Peachy.
They also made a song called Tearjerker which was the final song for See You On The Other Side.
Values Dissonance: Frontman Jonathan Davis grapples with his childhood experience of being accused of homosexuality by bullies on "Faget" and "Children of the Korn" and, although these songs are simply cathartic in nature, it isn't far-fetched to read an implied disapproval toward homosexuality into them, which isn't helped by the fact that Davis and Fred Durst toss homophobic slurs at one another wholesale on "All in the Family." However, this is clearly the product of a mere lack of tact rather than actual intent to convey a homophobic sentiment, which would simply be uncharacteristic of the band (the video for Korn's recent single "Hater" is dedicated to fans who sent the band accounts of their experiences of bullying, which includes a lesbian fan who briefly discusses being picked on due to her homosexuality).
