Mutagen Implementation Details

• We don’t interpret or write the “ID3v2 extended header”. An existing extended header gets removed when saving the tags.

  • https://github.com/quodlibet/mutagen/pull/631#issuecomment-1742118078

• We don’t support appended tags. They will neither be found nor updated.

  • https://github.com/quodlibet/mutagen/issues/78

• We always NULL-terminate multivalue text frames and ignore them when parsing
