Free Duplicate mp3 finder [closed]

"Try MediaMonkey. If you read this thread on Lifehacker it comes highly recommended. It has scripts for identifying duplicates by metadata and hash values. The free version of MediaMonkey does all you need.

The advantage of using MediaMonkey is that you can do a whole lot more with it. You can add metadata info to your music, find and add album art (it looks great when you have your entire music library like that), automatically rename files based on metadata. It's an incredibly powerful organization app; in my mind, nothing comes close (believe me, I've tried a lot of stuff)."

Fairly old program but with many awesome features is The Godfather. I have used it for years and it including Duplicate File Checking, batch Tag renaming and updating, automatic folder restructuring and many other useful features. It's also free and works on Windows 7/Vista/XP.
