["Unknown artist"/"Unknown album" even though files have tags. Missing tags also keep changing]

Signed up for beta and saw there'd been recent updates. Tried Full Rescan on 819 and it pretty much fixed the issue - but unfortunately I still had ONE album that was suffering from missing Artist & Album tags. 

So I removed my microSD, did a Full Rescan, reinserted it and did both another full & regular scan and now it seems to all be fixed! I can't find any missing tags anywhere now. Nice work @maxmp

Don't suppose we have an ETA on updates? We talking weeks? Months?

No hurry, I work/have worked in mobile development (albeit in art/design) so I understand these things can take a while. Just curious.

Thanks heaps for taking a look @maxmp.

Honestly I'm not 100% sure how they're so broken, it seems like most of the affected files would have been ripped from CDs purchased around the same time (somewhere between 2009-2010) so it may have been an issue with the iTunes release around then and my particular configuration. Or it could have been that they've been carried from drive to drive and library to library for so many years. It's odd because I can vividly remember some other albums I bought at the same time as some of these, but their tags are fine... it's inconsistent, the tags seemed to have broken at random.

If I still had the CDs I'd just do them again and be done with this problem, but unfortunately they're in storage in another country.

Mediafire is blocking that sample download by the way.

Thanks, noticed it seems to be blocking the old links too now. Updated the last one (https://www.sendspace.com/file/evvj3n)

@andrewilley I should probably have been more clear. I did use TagScanner to try and fix the tags once I found what they all were - I tried removing the semicoloned doubles, and even tried clearing the fields and re-entering the info.

The 3 files I linked above were actually mostly fixed. 01_We_Dance_On_The_Ruins_Of_The_Stup.mp3 and 01_Invisible_Colony.mp3 are still both missing Album Artist and Artwork fields in Poweramp. As I posted above with the 2 screenshots, that Strike Anywhere album (Iron Front) splits in two now instead of those files appearing under "Unknown album". But I guess you'd not be able to witness that without having the whole albums files. My bad there. Possibly because those files aren't showing any Album Artist whereas the others are, so it's splitting that album? 01_Fake_Empire.mp3 and that whole album seem to be tagged fine now after TagScanner.

The problem I'm having is that not ALL of the files were fixed by this method of using TagScanner, some even got worse and lost more tag info in Poweramp. Here's a file that was broken before TagScanner treatment and is still bust in Poweramp, failing to show Album, Album Artist, Genre and Artwork. Maybe this one will be of more help - https://www.sendspace.com/file/evvj3n

(Gheez, we're really exposing some of my angsty teen years guilty pleasure music from a decade ago with all these old files)

Well I'm totally at a loss for how to fix this my end. I've had to start looking around for a replacement app to use in the meantime until this is fixed. 😥

It's disappointing because Poweramp has basically proven to be the best option in most regards, it at least checks all my boxes... it's just seems to be the only player (out of the 15 apps I've tried) that has issues reading these tags, no others have created any "unknown" directories for any categories.

Double post, but I've been checking through and comparing the details of tracks in TagScanner to see if I can find any discrepancies. The only differences I can see come under the fields COMMENT ITUNES_CDDB_IDS and UNIQUEFIELD.

In most cases I can't see any correlation between COMMENT ITUNES_CDDB_IDS tags and any issues. I don't know what it represents but I'm assuming it's unimportant?

But that album I posted above that was split in two, "Iron Front" by Strike Anywhere, was interesting - the only difference I could see between the 5 tracks grouped w/ artwork and the 8 tracks grouped w/out artwork, was that the 5 tracks have a UNIQUEFIELD tag (containing links, eg.http://www.cddb.com/id3/taginfo1.html|3CD3N39Q192715711U23851D53EDFE7AB36784B76FB44A4FDE7CCP8) but the 8 don't. Otherwise there was no differences - again, not sure if this tag has any importance or not.

But yeah back to work, so I can't try anything out for a while. Are there any more advanced tag viewing/editing programs than TagScanner that are recommended, to see if I can fix this from my end in the meantime?

["Unknown artist"/"Unknown album" even though files have tags. Missing tags also keep changing]

Ok, so I worked through all the files with missing/duplicated tags in TagScanner on my desktop and re-copied them over. The number appearing under "Unknown album" by "Unknown artist" has dropped to 41 tracks and "Unknown genre" has dropped from around 140 tracks to 94. Some files that only had 1 or 2 missing tags (ie. some were missing "Album Artist")  have now lost even more tags.

Things are still a mess, basically. And I guess TagScanner won't let me check the tags on my phone directly, but copying files back again over to my PC showed the tags were all still intact, so they should probably be copying over with no issue.

The example album I've been using, Boxer, seemed kinda fixed... for a long while the TRACK TITLES were all empty though, even after Rescan/Full Rescan and an uninstall & reinstall. But I booted the app back up when I woke up, and with its initial scan it seemed to fix that issue itself. So, I guess that's one album totally fixed somehow. (You can also see the other issue I'm having with Poweramp in the screenshot though - the wrong track appearing as now playing on the bottom. It seems to take the tags from the track with the corresponding position in the general "All songs" list.)

The album with the file 6b6561 checked out, Iron Front, is no longer missing artist/album tags... but is now split into two albums for some reason.

Is there a .cue file in the same directory? I had the same problem. Turns out the .cue file defined the track names (albeit wrongly) but there was no band nor album definition in the .cue file. I removed the .cue and deleted the album from my phone, then copied the album over again without the .cue file. Full rescan and bingo, job done.

Just in case it's useful, I replied with the same method to this problem as well

Funny enough I came across this exact topic while trying to troubleshoot, but I couldn't see any .cue files (with Show Hidden Items checked in Explorer)

Thanks for taking the time to look into it. I've uploaded one of the files above to Mediafire, along with a couple others from different problematic folders just in case:

I tried a couple other old players I dropped along the way getting to Poweramp, and like I remembered they didn't seem to have any issues finding artist/album tag - none were listed under "unknown". But I did notice some of the problematic files were still missing album art with those players.

I looked into TagScanner though and may have found the problem? The files in question are appearing with doubled-up tags somehow. It'll take a while to fix them and I need to go to work, but I'll get back you with how that goes later.

Running files off a Samsung-brand micro SD on a Samsung Galaxy S9.

Even though all of my files have complete tags as far as I can see on Android/Windows Explorer, I have files appearing under "Unknown Artist", with other tags such as album or artwork also frequently missing. Sometimes even the track title is missing. The number of tracks missing info has fluctuated between 41, and 131 (where it tends to sit). It varies so much because it seems like everything I do to try fix it jumbles around the files some more (ie. some of the tracks that were appearing there before aren't anymore, and new ones have taken their place).

Here's what I've tried so far...

• Editing the tags en-masse in iTunes and re-copying the files over
• Simple Rescan (multiple times)
• Full Rescan (multiple times)
• Uninstall/Reinstall

I've attached images of one album. Here you can see the missing tags in Folder view in Poweramp, along with the fully-tagged files in Windows Explorer.

EDIT: should also mention I've tried several players before Poweramp and haven't encountered issues this severely with any files yet. Worst I had was some missing album artwork.
