What is singles cd?

A singles CD is a compact disc that contains one or more singles, or songs that have been released as individual tracks rather than as part of an album. It typically includes the radio edit or main version of the single, along with one or more remixes or alternate versions. Singles CDs are often released as a promotional tool to generate interest in an artist's upcoming album or to promote a specific song for radio airplay. They may also include bonus tracks or exclusive content, such as live performances or music videos. Additionally, digital singles have become more popular in recent years, with singles often being released exclusively through streaming services or digital retailers.
