This does not do ANYTHING

I loaded a playlist, as indicated in the directions, hit the auto detect, the dial spins, I hit apply changes, and all the songs in my playlist are exactly the same as the way they were when I started. ???? The only thing that works is if you have a single file, and a small section you want to adjust, then you can adjust that. But if you are trying to normalize a library of songs so you dont have to adjust the volume of each song, doesnt appear to be useful.
