Bittersweet White Light is the ninth studio album by American singer Cher.  The album was released in April 1973 by MCA.  It was the last solo Cher album to be produced by then-performing partner and husband Sonny Bono.  While many fans consider the album to be her best vocal performance, "Bittersweet White Light", composed mostly of covers of American pop standards, was Cher's first commercial failure of the 1970s.  It was Cher's first record released only by MCA, both in the UK and the US. "Needles and Pins" is a song written by Jack Nitzsche and Sonny Bono.  In his autobiography, Bono states that he sang along with Nitzsche's guitar-playing, thus creating both the tune and the lyrics, being guided by the chord progressions.  Jackie DeShannon tells the story differently, that the song was written at the piano, and that she was a full participant in the song's creation, along with Nitzsche and Bono, although she didn't get formal credit.

On the Hot Dance Club Songs chart, it became Cher's eighth number-one single, after being the greatest-gainer for its fourth, consecutive week.  On the Adult Contemporary chart "Woman's World" debuted at number 30, making Cher one of few artists to have appeared on that chart in every one of the last six decades.
