This has little to do with MP3TAG, but I hope, someone may have some idea as to what's happening.
I have an innioasis G5 media player, and use MP3TAG to do all my editing, I don't hold MP3TAG responsible for my problem, but would like to explain.
I have created several albums / folders of my music, the example one is a folder / album called Fast...in the past this has been named JAKFast, plus other names. When I scan the music using my G5, it creates multiple 'Fast' albums, as per the image, they all have the same correct artwork, but have different album names, although I have only scanned the Fast folder. I expected just a single Fast album.
All tracks in the album have various as the album artist, I checked with MP3TAG and all tracks have Fast as the album....don't understand how extra 'Fast' albums are being created.
Make sure that for an album the following fields are filled:
ALBUMARTIST, ALBUM, ARTIST, TITLE, optionally TRACK and YEAR.
If ALBUMARTIST is empty then many players cannot group together files by different artists.
Please show a screenshot of the tag panel for such an album when all files of that album have been selected.
TBH, I do not think that the folder structure has anything to do with the display of different files if the tag data is read.
Then only the tag data matters and if it is consistent for an album
Looks like you are using the HiBy music player app. Since this innioasis G5 media player is based on the Android 12 OS you can install other players. I have reviewed several others that may prove to be more helpful for you. Try Foobar as it is free. GoneMAD and Poweramp do have free trials as well for I believe 7 or 14 days. All are better players in my opinion. From your image it appears the Albumartist tag is not being used as a start, based on the individual Artist names under each Album.
Neutron is a bit more intensive, and with this particular player there would be little sonic benefit.
