Of course. Copy pasting here from another post:
"So I have the same problem.
I recently updated to Android Pie and did a factory reset. after reinstalling Poweramp (I previously also used the newest version), part of my library shows as Unknown artist - Unknown title - Unknown album. Funny thing is, the tags themselves are fine - when I go "Check Info/Tags", everything displays properly.
My phone is Xiaomi Mi A1, playing music from SD card.
Also on some songs only the Artist is missing and the rest of the info is displayed ok - but again, checking the tags, the Artist tag itself is correct.
Songs affected are .flac and mp3."
I used Mediamonkey for all my tags, they are certainly correct on my end so it's kinda baffling why some songs are problematic considering everything looks ok in the file itself and in any other program..
Do let me know if I can provide any other info/ files
