Jo Elizabeth Stafford was an American traditional pop singer, whose career spanned five decades from the late 1930s to the early 1980s. Admired for the purity of her voice, she originally underwent classical training to become an opera singer before following a career in popular music, and by 1955 had achieved more worldwide record sales than any other female artist. Her 1952 song "You Belong to Me" topped the charts in the United States and United Kingdom, becoming the second single to top the UK Singles Chart, and the first by a female artist to do so.

Traditional pop is Western pop music that generally pre-dates the advent of rock and roll in the mid-1950s. The most popular and enduring songs from this era of music are known as pop standards or American standards. The works of these songwriters and composers are usually considered part of the canon known as the "Great American Songbook". More generally, the term "standard" can be applied to any popular song that has become very widely known within mainstream culture.
