This has come up before, but not like I'm experiencing it. I only use MP3tag for files, so everything in my drives were tagged from Discogs through this program. Today, I found that every single one of my 100,000+ files are showing the "ERROR ID3V2.3 header parse error(ID3v1 id3v2.3) ERROR BAD MP3…

I figured it out. I'll occasionally dump files into Mixmeister for sound testing and that program was writing 'popularity' and 'key' into the tags, causing them to corrupt. I tested with a single clean file, turned off the 'iTunes Update' option and the bad ID3s are no longer corrupting.

[image] brandon210: I'm going to test and see if Rekordbox is the issue (unlikely as it only reads the metadata) Rekordbox has an option to write metadata to the file from it's database.

I just tested by changing the genre of a specific file and it looks like you're right, even though Pioneer/AlphaTheta claim changing data in RB only updates the RB database. Sounds like RB is wonking my tags. Awesome.

I think you can find that option here: Gear Icon (Settings) -> Advanced Tab ->Database section ->Write tag changes to ID3 file ->Enable or disable option

It doesn't look that option is in v6 or v7. All topics I've seen on the issue and replies from Pioneer seem to say it's a feature of the program and it can't be turned off, we can only stop writing the key to files. I'm wondering if the cue/beatmapping data is being written to the file and corrupt…

That should all be easy to test: Take a clean not corrupted file. Examine it with Mp3diags Tag it with Mp3Tag Examine it with MP3diags Load it in Rekordbox Examine it with Mp3diags Change a tag or save anything in Rekordbox Examine it with Mp3diags

@lyricslover examined the damaged file with exiftool and found a WXXX comment field with non-printable content, 2 more fields ID3_POP and ID3_TKE which look a lot like data from a DJ program or something similar - but most certainly not MP3tag. [image] brandon210: what would cause a file to cor…

Looks like that's the 'key' and 'popularity'. I don't have writing of the key toggled on, so it's odd to see it there. I'll open a ticket with Pioneer and see what they say. Thanks for that exif analysis.

I use the same program as part of my workflow before importing into Rekordbox. 6,000 corrupted MP3 file tag Removing the "Popularity" field de-corrupts the file, but also, takes all other tags with it. Do you have a way to remove this field without nuking the rest of the tags? I don't really fanc…
