Sweet Home Alabama was released by Lynyrd Skynyrd in 1974 and became one of the most recognisable Southern rock songs in American music, with its opening riff known even to people who cannot name the band. Online, the short riff travelled far beyond radio, becoming a shorthand sound for anything Alabama-related, from travel clips and sports celebrations to ironic jokes about the state itself. Its instant recognition keeps it useful: a few notes are enough to set a scene, signal a location and give a clip a familiar, upbeat feel.
