This music comes from the Mos Eisley cantina sequence in the original Star Wars film, released in 1977. The cue became one of the franchise's most recognizable pieces because its light, jazzy sound contrasts with the larger space-opera setting. Online, it spread through parody edits, gaming videos and sci-fi memes whenever a clip needs an instant alien-bar atmosphere. It still works so well because just a few seconds of the melody immediately signal Star Wars to a wide audience, much like the Imperial March.
