"It Doesn't Matter Anymore" is a pop ballad written by Paul Anka and recorded by Buddy Holly in 1958. The song was issued in January 1959, less than a month before Holly's death. "It Doesn't Matter Anymore" reached number 13 as a posthumous hit on the Billboard Hot 100 chart in early 1959, shortly after Holly was killed in a plane crash on February 3, 1959. The single was a two-sided hit, backed with "Raining in My Heart". "It Doesn't Matter Anymore" was Holly's last US Top 20 hit and featured the orchestral backing of Dick Jacobs. It was also successful in the United Kingdom, where it became the country's first posthumous number 1 hit.
