Lead single

A lead single is usually the first single to be released from a studio album, by a musician or a band, before the album itself is released.

During the era of the gramophone record, all music arrived in the marketplace as what is now termed a single, one potential hit song backed by an additional song of generally less commercial appeal on a single ten-inch 78 RPM shellac record. After the launch of the long-playing microgroove record in 1948 and the arrival of the 45rpm single the following year, singles continued to appear separately from albums into the 1960s. For instance, the early rock and roll market of the 1950s and early 1960s was very much focused on singles rather than albums. Songs such as "Heartbreak Hotel", "Johnny B. Goode", and "Tutti Frutti" only appeared later on album compilations of singles. Even through the 1960s, leading rock artists such as The Beatles, The Beach Boys, Bob Dylan, and The Rolling Stones issued songs such as "Strawberry Fields Forever", "Penny Lane," "Good Vibrations", "Positively 4th Street", and "Honky Tonk Women" as singles apart from any contemporary albums.

This changed in the 1970s as the popular music industry shifted to the album as its main profit center. Singles became advertisements for an album, the lead single conceptually defined as a foretaste of the album to come. On average a lead single will appear about one month before the album's release date. "Go Your Own Way" from Rumours, "Miss You" from Some Girls, and "The Girl Is Mine" from Thriller all roughly follow this pattern. This has become a common practice through the 21st century for album-oriented recording artists.
