Money was released by Pink Floyd in 1973 on The Dark Side of the Moon, written by Roger Waters. Its intro was assembled from recorded cash registers, coins and tearing paper spliced into a loop, an early example of musique concrète in rock. Released as a single in the United States, it became one of the band's most recognisable tracks. Online, the short intro loop is separated from the full song and reused as a standalone money sound effect for memes, edits and finance videos.
