A while back i was looking for a program to search my music library and find duplicates and smilliars in my files. I tried alot of them and this one seems to work the best imo so i figured i would share. I used it on my g/f's collection (about 5,000 songs) and on mine (27,513 songs) and have had no issues or hang ups.
I did find however that it can be faster to break it into chunks. For example a-f, g-m, etc if yours is huge like mine instead of one big tackle.
The screenshot of the gui is an older version. It's nice and simple, its fast, and its damn accurate.
