"Money" is a song by the English progressive rock band Pink Floyd from their 1973 album The Dark Side of the Moon. Written by Roger Waters, it opened side two of the LP record.
Released as a single, it became the band's first hit in the United States, reaching number 10 in Cash Box magazine and number 13 on the Billboard Hot 100. "Money" is noted for its unusual 7/4–4/4 time signature, and the tape loop of money-related sound effects (such as a ringing cash register and a jingle of coins) that is heard periodically throughout the song, including on its own at the beginning.
"Money" was performed during Pink Floyd's reunion show, for which Waters rejoined the band (after more than two decades), at the Live 8 concert in London in 2005, along with "Breathe" (including the reprise that follows "Time"), "Wish You Were Here" and "Comfortably Numb". Unusually for a live Pink Floyd performance, at Live 8 the band kept the song's solo to three choruses, as it is on the album.
