Death by Glamour was composed by Toby Fox for Undertale, released in 2015, as the battle theme for the robot entertainer Mettaton. Its glam-rock arrangement matched Mettaton's flamboyant television persona, and the track quickly became one of the game's most recognisable pieces outside its soundtrack. Fans shared it in edits, animations and streams, while its dramatic opening made it easy to reuse as a short reveal cue. It remains popular because it instantly signals confidence, spectacle and a deliberately over-the-top entrance.
