Who sings the song that goes, "When we pretend that we're dead"?

I heard it on the radio today. Like, I was minding my own business lobbing grenades off the roof of the gun store down onto the traffic below when the cops showed up and started chasing me for no reason. So, anyway, I hopped on my motorcycle and started running from them, and this song came on the radio. And I’m wondering who sings it…
