They've also had two tracks hit the Gold certification too.
Killswitch Engage's classic track 'My Curse' has been certified Platinum in the US.
That's the equivalent of 1 million sales, which is absolutely huge.
The track appears on the band's '06 album 'As Daylight Dies' which was certified Gold in 2009.
The band have also had two more tracks certified Gold this week. That's the equivalent of 500,000 sales each by the way. Those tracks are 'The End Of Heartache', taken from their '04 Gold certified album 'The End Of Heartache' and their cover of Dio's metal classic 'Holy Diver'.
Lots to be proud of here.
SO, here's 'My Curse':
Here's 'The End Of Heartache':
And here's 'Holy Diver':
The band released their latest album 'Atonement' last year.
