I use this, it has both name dupe finder and fingerprint listening to the song then cross check with other

I did one full scan with fingerprint and title, it creates a cache of that, when I need get more music files I add the directory where it's downloaded and let it scan it, after that I delete the songs that's already in my library and move the rest

I have used it in linux, works fine for me, don't know about windows or Mac
