Hi, I have two AIFF files here. Both tagged with ID3v2.3.0. They are both tagged with the same Artist, Title and Album tags. The only difference, as far as I can tell, is that one additionally has a 'Tagging Time' tag, but I can't imagine that's the reason that MP3tag is unable to recognise the other tags in that file?

**Edit** : _Removed links to test files_

Would love to know if anyone can figure out what the difference is between these two files.

Thanks

The second file is truncated. The ID3v2 header reports a size of 1184 bytes while the actual data in the file is way smaller.
