If you’re like me and have an inordinate amount of MP3s sitting about, and alot of them have wrong or missing ID3 tags; then you’re in luck. There’s this nifty little application called Picard made by a site called MusicBrainz. You tell it where your music is, then let it loose on your collection. It’ll go through and find all the stuff that isn’t tagged correctly then it’ll query their servers and find out what artist, album, track number, etc; everything is. All you need to do after that is approve it’s suggestions and tada! A cleaned up music collection.
