Sure there are plenty of MP3 tagging programs out there. Most of them even check Amazon or Google and fix your tags for you. What sets iEatBrainz apart from the rest is that it actually submits your track to the EatBrainz music database and verifies you have the right song. It does acoustic sound matching so if you have an mp3 cryptically titled 01.mp3, iEatBrainz will figure out its really Black by Pearl Jam and rename it accordingly. Another high quality app by Jay Tuley the author of CD To which I reviewed in my last post.
