skwire, you are da man!!
I love this program. Let me tell you my history with this issue:
Before the days of good desktop indexers (Google Desktop, Everything, X2, Copernic, etc.) it was very important for me to catalog the mp3 files on my computer. I eventually settled on MP3 Collector, which was great at the time. Since then, it has stopped being developed for the most part. The BIG complaint with MP3 Collector was that it would export a list of the UNIQUE albums that you had. It would give you just a list based on each mp3 file. So if an album had 12 songs, there would be 12 lines in the list. But all I wanted to know is which albums I have. The developers always insisted the program wasn't meant for that because mp3 files are not physically grouped or whatever reason they gave. They were basically saying they just didn't want to do it. Then they said they MAY do it later. Years later, nothing has happened.
The whole reason why i want this is because when I walk into a record store, I want to know which albums I have and which ones I don't, so I don't waste my time buying something I already have. So this program is EXACTLY what I've been looking for.
