Hello! I ran into a problem that the way some of my songs give out an error. I would like to change them all to ID3v2.3 (ID3v1 ID3v2.3), since I play such audio correctly. What do I need to do for this?
You would have to scan your files.
This thread links a couple of tools to do that.
If the files can be repaired - ok.
If not ... you would have to try to get working ones.
What do the linked tools report?
The audio part will not be touched with Mp3tag.
Mp3tag only manages the metadata.
Your songs can play without hearable problems but still can contain problems with metdata.
Please use the mentioned tools to check your mp3 files if the audio part AND the metadata part can be fixed.
As soon as there are no more tag errors in Mp3tag, we can show you how to unify the ID3-Version for your files.
That looks like something bad has happend to your files.
You could try to repair them with the hammers - the bubble help shows which methods are applied, you could try with the fewest methods and see if the serious errors go away or otherwise use more and more methods.
Another option could be to use MP3tag and cut the tag of a test file, check that file again with mp3diags and see whether the problems are gone.
If not, then you have to rely on MP3diags.
