Hi!

Do you still have the mp3 somewhere? I'd like to try because it works with the MP3 files that I use.

Hi!

I have the same issue after updating the metadata with Chinese, as shown in the code below.

updateMetadata(file, (metadata) {
  metadata.setTitle('歌曲');
});

It will throw the same error message after executing the same code again, and when i use the Mp3tag to check the song, it display the message: ERROR: ID3v2 tag parse error; ID3v1 (ID3v1 !BAD ID3v2). It seems that the first update with Chinese corrupted the metadata structure.

I fixed this issue in PR #98.
