Each song is numbered on my set list. I have a separate FS3X foot switch that allows me to quick scroll through the songs on the pedal. This makes it very easy to change the set list or play requests.

If you purchase extra memory cards you can increase the amount of storage space on most looper pedals. I currently have 80+ songs (saved as WAV files) on my pedal, and have only used a small percentage of my available storage space.
