Another problem is tags. I have 40,000 tracks (not all of them I need, I plan to rethink my methods of collecting music and get rid of what is not fun) but a smaller part of them with tags. This is a very long job. Even if you use MusicBee tools or other tagging services, it is very long, because there are a lot of wrong genre tags on MusicBrain, Discogos. Everything needs to be manually entered, I browse my 2 main sites, where I get information about tags.
At the end of the day, if you want MB to organize your files in the semi-complex structure you wish to maintain, then all -
each and every single one - of your music files needs to be tagged according to how you wish to implement that structure. Every file from every album will need to be consistent. MusicBee does not manage files by folders. It manages files by tags, as it should. If you wish to incorporate a particularly detailed directory structure within MusicBee, you're not going to be able to do it without
MONTHS of correcting your tags.
The problem is that not all tracks on an album contain the same information. I noticed that somewhere the year is not marked, somewhere the name of the album is missing. All this can be fixed if I had 100 albums, not thousands
If you're not willing to fix these thousands of albums, then you won't have your desired structure within MusicBee and should stick with whatever file manager you were using before, because all the tracks on an album
must contain the same information album-level information. MusicBee is a tag manager, not a file manager, and if your tags are all over the place, then it will display your files all over the place.
I proposed this in one of your threads, but the main issue here is you're jumping the gun. You need to get
all the tags in
all the thousands of your albums consistent and afterwards figure out how to have MusicBee organize them. You won't be able to do it backwards like you're wanting.
