DEJA VUE  I used MC for some time and I am not pleased with what it is offering. In order to create new entry you have to scan its bar code with... !? So, instead of making things easier, developer pushes us to another purchase just for using this software!? There are problems even when you try to create new entry (opera CDs for instance) which is consisted of 2 or 3 CDs. It will create two entries and then you have to insert second one into first one, and then... I think - two stars for developer's effort is quite enough.

BYZCATH  Knocks Readerware AV out of the box, but it needs a little work yet. I have been having trouble with the entry window when trying to scan in barcodes for a CD - it disappears. When I put the CD into the computer and have the program scan the CD, it does very well. It would be nice if it would enter the price for you, like readerware does. Overall, for 1.0, it is a great program!
