Hallelujah was written by Leonard Cohen and released in 1984, then covered by countless singers until its chorus became a shorthand for relief and revelation online. This short Adeleina version isolates the title word as a standalone soundboard clip, which is why it travels so well in short videos and chats. Instead of using a full song, creators borrow just that recognisable lift to mark a breakthrough or a blessed moment, and the contrast between the grand, sacred tone and ordinary situations keeps it useful for both sincere posts and jokes.
