The clip is listed as 1. U Are Not, with no artist, album or source work attached, so its exact origin is not documented. That has not stopped people from picking it up, because short, reusable music excerpts travel easily between edits, stories and soundboard collections. At just over thirty seconds, it fits the length creators want for background music without needing a full song. Its continued use comes from that practical size and its simple, memorable title, which makes it easy to find again for another short video.
