* SugarWiki/AwesomeMusic: "My Curse". Arguably Killswitch Engage's most popular single, and it shows. It was featured in ''VideoGame/BurnoutParadise'' for a reason...
* CoveredUp: Their cover of [[Music/RonnieJamesDio Dio]]'s "Holy Diver" is more famous to many people of younger generations than the Dio original due to the Killswitch version having a funny video to go with it. This is not the case in the metal community, though, since the song is a SignatureSong of one of the most respected metal musicians.
* EnsembleDarkhorse: They are the most respected mainstream metalcore band.
* SugarWiki/HeartwarmingMoments: Howard and Jesse get along great, and Howard's shared the stage with him plenty since leaving the band.
* MisattributedSong: Once again, "Holy Diver". There are definitely people out there who think Killswitch wrote it.
* RefrainFromAssuming: "My Curse" is often called "This is My Curse".
* SignatureSong: More than one:
** Howard Jones:
*** "The End of Heartache"
*** "My Curse"
*** "Holy Diver"
** Jesse Leach
*** "In Due Time"
*** "My Last Serenade"
* SongAssociation:
** For many video game fans, the first time they heard Killswitch was during the end credits of ''Film/ResidentEvilApocalypse'' during which plays "The End of Heartache".
** "My Last Serenade" was featured in ''[[VideoGame/TrueCrimeStreetsOfLA True Crime: Streets of LA]]'' and ''[[VideoGame/FalloutBrotherhoodOfSteel Fallout: Brotherhood of Steel]]'' (along with "Fixation On The Darkness" in the former and "Temple From The Within" in the latter).
** A lot of racing game fans associate "My Curse" with ''[[VideoGame/{{Burnout}} Burnout Dominator]]'' (which is later reused for ''Paradise''). Plus, it was featured in ''VideoGame/SleepingDogs2012'' as well.
** "My Curse" also got some mileage from being featured in ''VideoGame/GuitarHero III'', and ''VideoGame/RockBand'' later having its own Killswitch Engage music DLC.
** "Reckoning" was used in ''Madden NFL '10''.
** [[Wrestling/CMPunk "This Fire Burns"]] appeared in both ''WWE [=SmackDown=]! vs. Raw 2011'' and ''WWE All Stars''.
