Hey, I need a mass program for my Macbook that'll do mass ID3 tag editing. Basically need to edit MP3s and rename them based on the tag. I basically receive a ton of music and need to check all the ID3 tags to make sure they're proper, then rename them accordingly based on the ID3 tag. For example, the file needs to be renamed off the Artist and Track Name like this: "Artist_-_Song_Title.mp3" Any easy program that can mass edit them up for me? I'm down to pay. Thanks!
