When I sync mp3 files from my Windows desk computer to my Galaxy S20 FE, a significant number of albums (about 30) are missing their 1st track, and all those "missing" tracks are filed under Artist "unknown". A small number of albums lost their 1st and 2nd tracks, or their first three tracks. Two albums were lost in their entirety.
I did try another, third party music app, and the problem is exactly the same, so it appears to be an issue more with the way that mp3's are stored than with the Samsung music app.
