If you have a lot of music on MP3 this ID3-Sync program could be useful to you. It lets you edit ID2 and ID3 tags on your MP3 files, synchronizing them at the same time with other files that are already synchronized. In other words, changes you`ve already made to the tags of the original MP3 are automatically changed in other files, saving considerable time.
It lets you obtain the information (directly from the popular FreeDB) that correspond to the data of each MP3 song, in order to edit the correct fields.
