automatically tag mp3 collection using shazam-like acoustic fingerprint

Question

is there any software freely available to clean up the tags in your music collection , based on some sort of audio fingerprint type technology (like how 'shazam' app works on the iphone) combined with a freedb-like database? my music collection is a 900 GB mess and clementine does not index files as well as i would like it too, because many songs are missing tags.

Answer 1

Try MusicBrainz Picard:

Picard supports the majority of audio file formats, is capable of using audio fingerprints (PUIDs), performing CD lookups and disc ID submissions

It's probably the number-one application for such purposes.
