So, I found this great article shows you how to clean up any messy ID tags on your MP3s. One of the tools is an app called MusicBrainz Tagger, which looks at your MP3, compares it to a database, and tags it with the correct artist, album, and track info. If it can’t identify the track, then you can manually lookup the information and tag it yourself. Great tool to clean up all my files in iTunes.
