Painkiller is the title track from Judas Priest's 1990 album of the same name, recorded by the English heavy metal band after drummer Scott Travis joined the group. The song became a landmark of speed metal, praised for its relentless tempo, twin-guitar attack and Rob Halford's high, screaming vocals. Its opening has since become shorthand for intensity in metal culture, sampled and clipped for workout videos, gaming edits and reaction content, where a few seconds are enough to signal that something extreme is about to happen.
