Ever had a bunch of MP3’s without proper name and tags? You could obviously buy your MP3’s on iTunes in the first place, but sometimes it is just handy to give those MP3’s the proper tags. In comes iEatBrainz (freeware) which doesn’t need any help from you or the filename to decide what song it is. To do this it calculates a audio fingerprint of the music and compares this to the data at MusicBrainz.org. Then it downloads the tags and it even updates iTunes for you. For me this is the best tool ever because I had some MP3’s that needed this tool badly.

Only one downside: some songs have appeared on so many albums that you have to make sure that the tool selected the right album. Maybe a new feature might to have the tool look on what songs you have and then decide what album they make up?
