Released in 1983 as a single from Madonna's self-titled debut album, Holiday became her breakthrough hit and one of the defining dance-pop songs of the decade. Its message of taking a day off and celebrating together helped it cross from radio and dance floors into films, adverts and party playlists. Decades later, the chorus remains instantly familiar, which is why creators reuse it for travel, celebration and summer content rather than treating it as a period piece. Its optimism still feels current.
