I would seriously check the files for integrity and repair them with mp3val, mp3diags and foobar2000 before you do any further tagging. And that is a file from the same folder - so that is apparently no criterion. You should have a look at all the files as they all have different peculiarities, e.g. As I edited almost 5 GB of files in one go it would be really unfortunate if I cant rescue the songs. Is this a known issue and/or is there a fix available? I undid the changes on some files to see if the files would get restored back to normal, but to no avail.
I am absolutely sure that the issue stems from the editing as I tried to open the files with different music players (Windows Media Player, VLC) and on different systems (Windows 10 Laptop, Android Smartphone) to eliminate any possible error source.
Unfortunately though, I discovered an issue that occurred right after I was done editing: All of the modified files were kind of corrupted, i.e. It all went very well and I was very happy with how my library looked afterwards. I mainly added some album covers and fixed some missing tags. I am new to MP3Tag and used it for the first time recently.
