A "comeback single" is a song released by an artist after a period of absence from the music scene. This type of single often aims to reintroduce the artist to their audience and regain popularity. Comeback singles can be crucial for artists looking to revitalize their careers or shift their musical direction. These singles are typically accompanied by promotional efforts, such as music videos and live performances. Successful comeback singles can lead to renewed interest in the artist's work and may even chart well on platforms like Billboard or Spotify.
