Super! I was impressed by the report function that actually lays out what it is going to tweak. Suggestion, just for a quick take, take one of your songs, use the auto master a WAV file and when it asks for a reference load the @master RMS.aam. It is simply amazing what it does (it will take several minutes to run through the whole process depending on your computer's speed and ram). You can then look at the report to show you what it did.
When you play the mastered file you will really hear the subtle differences. When you get more into it, some of the options are tremendous. It has a 100 band EQ - amazing. :D
