"And So It Goes" is a lyric poem written by Billy Joel in 1983, though it was not released until six years later. It appeared as the tenth and final track of his album Storm Front. The original 1983 demo was released on the 2005 box set My Lives. Joel wrote the song about a doomed relationship with model Elle Macpherson. Their relationship was dramatic, as Macpherson was only a teenager while Joel was reaching his mid-30s. Joel dated Macpherson for a brief time shortly before becoming involved with model Christie Brinkley, who would ultimately become his second wife. The song is unique for Joel as it is written in iambic tetrameter. In the original demo version of "And So It Goes", Joel sings the melody simply, accompanied by a simple piano backdrop, in a style very reminiscent of a hymn. On the 1990 album version, Billy Joel sings and plays all the instrumentation (piano and synthesizers). The official video is a live take in front of a concert audience.

The single peaked at No. 37 on the U.S. Billboard Hot 100 and No. 5 on the U.S. Adult Contemporary chart in 1990. It has been covered by many subsequent artists (see "Cover Versions" below). The King’s Singers and others have developed several vocal harmony arrangements of the song, which are often performed by high school and college choirs.

On November 16, 2010, during an interview on the Howard Stern show on Sirius Radio, Billy Joel was asked what song is his best work that is least appreciated. To answer this question, he played "And So It Goes".
