I actually bought the program. Their registration process is way over kill for such a small app. I have a very large library (around 800 GB) so it took quite a while to create a list but when it was done I tried a dozen or so and they seemed to work well. It is going be kind of tedious with such a large library and so much missing content (I had to re-import my whole catalog when iTunes hiccuped). I wish you could script it to look for artist, album, etc and then group them together so you could install the correct data once instead of tune by tune. Their other product CoverScout could stand more automation also.
