Foster the People's Pumped Up Kicks began as an indie-pop hit, but American industrial band 3Teeth reworked it into a much heavier version built around distorted guitars and aggressive vocals. The cover found a second life online, where editors use the familiar chorus to create an unsettling contrast in fan videos, workout montages and horror-tinged edits. Its lasting appeal comes from that clash: listeners recognise the tune instantly, yet the sound feels completely different from the original.
