I have a large collection of MP3s that were ripped on a Windows PC and I want to add them to my iTunes library on my Mac. The problem is there is either no meta data for the files or the info that is there is wrong or badly formatted. The collection is organized with each album in its own folder, so I am able to tell what is what. Is there a program for OS X that would allow me to dump an album into it and rename all of the files and set meta data according to a certain format and get this track info from Amazon, Gracenote, or similar? Also, I would like to set the album art for each track.
