I downloaded several musics from YouTube and was able to listen to them normally, but when I used mp3tag to change some tags, they suddenly became unavailable. I tried using mp3val to repair them but it didn't work (it said it worked, but they still can't be opened).
What can I do ? There are about 50 broken files and I don't really have the time to download them again

Odds are these aren’t properly formatted. See here for similar issues.

> What's the source of the files (I'm guessing a random website that converts from Youtube) and have you [checked the original files for errors](https://community.mp3tag.de/t/how-to-check-files-for-errors/44633) (preferably with MP3 Diags). Most of the YouTube converters are now providing files that are actually MP4 dash disguised as MP3. Due to the nature of those sites, it’s impossible to contact them and make them aware of the problems they are causing.

Just to be sure: the files themselves are corrupted thus you cannot listen to them anymore - and not the data in theirs tag fields?

` `
As for downloading from YouTube: how did you do that? I both both curious what method you used - but also I would like to advise you to use from now on the YouTube Video and Audio Downloader (Dev Edt.) add-on for Firefox [see info at [YouTube download in high quality](https://community.mp3tag.de/t/youtube-download-in-high-quality/18443/)]
