The sound comes from the short musical theme associated with Roku streaming players and TVs, which many viewers hear when a device starts or a channel opens. Fan remixes extended that brief cue into longer loops for edits and soundboards, and this second version keeps the same recognisable melody in a form creators can drop in whole. It spread through meme pages and short video edits where a familiar startup sound instantly sets a streaming context without needing any explanation or on-screen branding to land.
