While Band-in-a-Box can be used for live performances, some people find the starting/stopping and Jukebox options not to their tastes, and I have heard of others saying they prefer to not have to worry about the way the cursor moves through the song. You can set up the Jukebox to a specific folder that contains your songs and use that for live performances if you so desire, but depending on your preferences, you may also prefer using your rendered files and loading up a setlist for yourself outside of the program either just in the file explorer using Windows Media Player or through a third party application of some sort.

Cheers,
