Does anyone know of a tool which will read mp3 audio information directly (not the tag information), generate a fingerprint of that audio information, recommend tags based on the fingerprint and retag your MP3 collection? Last.FM released a console application which did all but retag your collection.

The MusicBrainz Picard tagger sounds like exactly what you are looking for. It fingerprints your music regardless of existing tags and will add the correct tags.

It's not the most intuitive tool to use, but it is very effective. I have been using it a lot lately and it successfully tagged 6000+ tracks that had incorrect metadata.

Thanks for the suggestion! I used Picard last week and it incorrectly labeled a bunch of my files. shrug – user28496 Feb 17 '10 at 0:39
That's interesting. The biggest "mistake" I've seen it make is assigning an album that I didn't like when a track appeared on multiple albums. Really there were multiple right answers and it chose one that I wouldn't have picked. What sort of mistakes have you seen? Also, what percentage of files was it incorrect with? 10%, 20%, 90%? – Nick Martin Feb 17 '10 at 19:22

You can try out Tunatic

Love that song but don't know what it is? Tunatic can tag it for you!

Ever thought ‘what is this song?’ Let Tunatic hear it and you will get the artist's name and the song's title within seconds. Tunatic is the very first song search engine based on sound for your computer. All you need is a microphone and Internet access.

Tunatic is freeware.

Thanks for the suggestion! It doesn't look like Tunatic tags your MP3s for you. – user28496 Feb 17 '10 at 0:39
