A set list, or setlist, is typically a handwritten or printed document created as an ordered list of songs, jokes, stories and other elements an artist intends to present during a specific performance.

Setlist Predictor is an AI-based tool designed to provide concert-goers with predicted setlists for their chosen artists. It aims to prepare music fans ahead of concerts by giving them an idea of what songs their favorite artists are likely to perform.

You can usually check the venue website, or your ticket, or the artists' social media sites for when they'll be performing. I know it takes all the fun and risk out of guessing, but hey, at least you'll know for sure!
