For the musical duo:
* CoveredUp: Their drastically altered version of "Crimewave" from {{HEALTH}}'s self-titled LP is better known than the original. [[http://www.youtube.com/watch?v=OCwm08sTA5U Compare]] and [[http://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.
* CrowningMusicOfAwesome: "Not in Love (ft. Robert Smith)" definitely counts. Robert Smith of 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''.
* HellIsThatNoise: There's that strange noise that repeats throughout "Plague" that sounds almost like a warped whale song. It sounds a bit like CC watched the trailer for Prometheus and went home to make a song.
** The ''entirety'' of "I Am Made of Chalk".
* 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 {{Swans}}.
* 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 lillies and candles]] on stage. Sad and touching already, but towards the end of the show, [[http://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.
