Seven Nation Army (White Stripes)

One of rock's most iconic bass lines — except it's a guitar run through an octave pedal, a trick that became accidentally mythological. Jack White strips the arena-rock format down to its skeletal core: two notes repeated with increasing menace, a vocal delivered more like a spoken dare than a sung melody. The production is sandpaper-rough and deliberate, rejecting polish as a philosophical stance. Lyrically it's vague enough to project onto — a story about being chased, or perhaps about the exhaustion of fighting systems larger than yourself. It became an anthem precisely because of its abstraction. The cultural footprint is enormous: sports arenas, protests, film trailers. Best encountered in a context that needs a spine.
