American Top 40 was the long-running American radio countdown created by Casey Kasem and Don Bustany, syndicated nationwide from 1970. The clip here comes from the broadcast of July 3, 1982, the countdown for chart week 823. The show's brassy intro jingle became a cultural shorthand for pop-chart authority across two decades of radio. Today creators sample it as a quick nostalgia trigger, a way to lend any list or ranking the gravitas of a national countdown, or to set the mood for eighties music content on short-form video platforms.
