Three Little Birds was written and performed by Bob Marley and the Wailers and appeared on the 1977 album Exodus, where its simple chorus about not worrying became one of Marley's most recognisable messages. Over the decades the song grew into a global feel-good anthem, covered widely and quoted in films, adverts and everyday speech. Short excerpts now circulate on soundboards and social video because the opening reassurance is instantly recognisable even without the full song, making it a quick shorthand for calm, optimism and letting a bad moment pass.
