A concert setlist is a list of songs that a musical artist or band plans to perform during a live concert. It serves as a guide for the performers and helps organize the flow of the show. Setlists can vary from one concert to another, depending on the venue, audience, and occasion. Fans often look forward to seeing their favorite songs included in the setlist, and some even track changes in setlists from different concerts. Many artists, like Taylor Swift or Coldplay, may also include special surprises or unique arrangements in their setlists to enhance the concert experience.
