!! 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]]'''.
* TearJerker:
** "Tell Me What to Swallow."
** "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.

!! For the video game:

* EarWorm: The music that plays when you grab the magic hat. Can also qualify as MostWonderfulSound.
* WhatDoYouMeanItWasntMadeOnDrugs: The characters, art, and scenery are... ''Surreal...'' To say the least.
