Hello is the lead single from Adele's third album, 25, released in 2015, and its opening line became one of the most quoted introductions in modern pop. The song topped charts around the world and its video was widely shared, which helped the first few seconds travel far beyond the full track. On social media, creators began isolating the greeting for reunion jokes, parodies and dramatic entrances, where the familiar voice does most of the storytelling. Its simplicity keeps it useful years later, because almost everyone recognises the line instantly.
