Can't See Tag Changes in Windows, ITunes, or WMP? Read this.


If you are using MP3Tag, which is awesome BTW, but don't see the changes you make to the tags outside of the program such as in Windows 7, ITunes, or even Windows Media Player then the problem is probably not MP3Tag, it's likely the MP3 file is somehow corrupted.

Spent quite a bit of time updating MP3 tags using this program and thought I had cleaned everything up. However then I noticed that several of my songs were not visible in WMP or ITunes. I also noticed that all the tags that I had spent all that time putting in were note showing in windows explorer. I tried to edit them using the file properties in windows explorer and it wouldn't let me. I went back into MP3TAG and surprisingly the tags were still showing correctly there.

After doing quite a bit of reading, I found a utility called MP3VAL that is basically a scanner/repair utility for MP3's. It scans the files and identifies which have problems. Not surprisingly all the ones that wouldn't show in ITunes/WMP and wouldn't show the Tags in Explorer all had problems. However, several others had problems as well. I then ran the repair function in MP3VAL and, presto, all the files now show as they should and my previously entered tags even showed up.

The link to the utility is below. Hopefully this will save some other newbie a lot of frustration that I went through.

Select the first option which includes the frontend and core engine. Unfortunately there is no installer but cnce downloaded, simply unzip it and copy to your Programs directory in a folder you create. Then just create a shortcut to the frontend executable on your desktop if you like.

Have fun...


Actually, these programs rely on a proprietary database that has to be filled with the means of the program. So any outside changes to the tags will only take effect if the library is updated form within the program.
You are right that sometimes even updating does not show the modificactions.
But there has been a discussion in this forum which program then checks and fixes possibly corrupt tags. Mp3val in only one of them.
Members of this forum also frequently quote Foobar2000 as a tool for repairing. Many routes lead to Rome.
There is another source of trouble: APE tags. As they supercede MP3 tags some modifications to MP3 tags do not show as long as APE tags are present. You then have to delete these tags first.
The world is so complicated!


how can we know that ape tags are present? and how can we delete it? is mp3tag sufficient to recognize the ape tags? then how? plz suggest, thanks.


I think you should start by reading the FAQ first.
