!! For the musical duo:

* SugarWiki/AwesomeMusic: "Not in Love" definitely counts. Robert Smith of Music/TheCure on vocals, Alice Glass' breathy ones joining in at the bridge, and Ethan Kath's newly polished production skills really make it for this one.
** "Alice Practice," the song that introduced them to the world. Basically what would happen if you captured a chiptune band and a female fronted hardcore punk band and made them fight. It's ''glorious.''
* BrokenBase: Post-Alice departure, some fans are divided on who to side with regarding quarrels between Ethan and Alice. Alice has claimed that Ethan stifled her creative input, while also saying she's the one who wrote most of the lyrics for the group's songs, while Ethan has maintained that he's the one who has had most of the creative control, even prior to Alice joining him to form Crystal Castles (and has kinda passive-aggressively mentioned how some of CC's more popular songs did not even feature Alice's vocal work).
** The fans are also divided as to who they favour as the vocalist, Alice or Edith.
* CoveredUp: Their drastically altered version of "Crimewave" from Music/{{HEALTH}}'s self-titled LP is better known than the original. [[https://www.youtube.com/watch?v=OCwm08sTA5U Compare]] and [[https://www.youtube.com/watch?v=1cLxbAQMeWE contrast.]]
** Also happened after the release of "Not in Love," as many people didn't realize it was originally a Platinum Blonde song.
* NightmareFuel:
** Once again, "I Am Made of Chalk." It's probably one of the weirdest songs they've put out, consisting almost entirely of modulated wailing and screaming. The amount of speculation as to just what the song means makes it reach levels of MindScrew equal to the work of Music/{{Swans}}.
** [[http://cdn2.pitchfork.com/news/60224/96f1edde.jpg This image]] of the two wearing weird black ''things'' on their heads and staring at '''[[TheFourthWallWillNotProtectYou you]]'''.
** [[https://www.youtube.com/watch?v=zSsvcT9cDZ0 The official music video]] for "Magic Spells". It's under a minute long and revolves around a person resting in a sleeping bag inside a cabin while a man is outside in the background. The man then enters the cabin and [[spoiler:nonchalantly drops a cinder block on the sleeping person's head]].
* SugarWiki/SweetDreamsFuel:
** "I Am Made of Chalk"; once you get past the chaotic opening, it morphs into a beautiful synth composition only made off-putting by the strange warbling sounds throughout.
** "Child I Will Hurt You" is the closest that they've gotten to making a lullaby.
* TearJerker:
** "Tell Me What to Swallow", a harrowing acoustic ballad with lyrics from the perspective of a victim in an abusive relationship choosing to stay. Alice's agonizing vocal delivery makes the song even harder to stomach.
** "Child I Will Hurt You" qualifies as well, a rather soft song that sounds almost like a lullaby.
** Crystal Castles tried several times to get in contact with a fan named Connor who was dying of cancer. He died at the age of 18 one night before a performance, and Alice proceeded to set up a [[http://wearecrystalcastles.tumblr.com/post/36591848313 shrine complete with lilies and candles]] on stage. Sad and touching already, but towards the end of the show, [[https://www.youtube.com/watch?v=hHUMkGQwx98 Alice broke down in front of the shrine and sobbed into the microphone]] while the crowd is still cheering for the show they've just seen.
** Hearing the news that Alice was leaving the group was undoubtedly this for many, with some even going as far as proclaiming that her departure spelled the end of CC, but her allegations of Ethan sexually, emotionally, and psychologically abusing her imply that--at the very least--the two's separation was not amicable.
