I have a large music collection where every other mp3 file has id3 v2.1, v2.2 and v2.3 tags. I don't know why but some of these files have valuable info. stored in the v2.2 tags but not in the v2.3.
I use mp3tag to manage, edit and format all my mp3s, but the tool doesn't offer any way to compare data stored in different version of id3.
Is there any tool capable of doing this on Windows?
