Once adding tags to an MP3 file, how can we add these tags to both id3v1 and id3v2 on the same time, otherwise, how can we copy id3v2 tags into id3v1 tags.
Thanks in advance
Kid3 audio tag editor, a tool that can be used to edit the tags of MP3, Ogg, FLAC, MPC & WMA files in an efficient way, convert between ID3v1 and ID3v2, set the tags of multiple files, generate tags from file names or vice versa and import from freedb, MusicBrainz and Disco, is now at version 3.1.1
Kid3 Tag Editor comes with a huge number of features and it's capable of converting between ID
Might be the file includes both id3v1 and id3v2 tags, and one of the tag sets is wrong. Have you tried opening the file in a tagging application (something like easytag or MusicBrainz Picard) and resaving it there?
