The Mii Channel launched with the Nintendo Wii in 2006 as the app where players created their Mii avatars, and its smooth lounge-jazz background music, composed by Nintendo's Kazumi Totaka, quietly became one of gaming's most recognisable tunes. In the 2010s it took on a second life online as creators sampled it in remixes, covers and ironic edits, turning a menu theme into a full-blown meme. A decade later it still signals instant cosy nostalgia, and even a few seconds of the melody tells viewers exactly what kind of video they are about to watch.
