redwing I missed your post #12. It does exactly what I was looking to achieve. Thank you.
I do need to keep often double tracks in different folders which annoys me but didn't yet find a solution to keep things continuously being "organised". This problem is apparent with EDM music, not with other genres where the tags are much simpler, like Classical, Pop, Jazz etc.
Files are tagged in the following manner, in the
artist field: Artist1; Artist2 etc
album artist: Artist1
So if I have a song for example like the above, Maroon 5 - This Summer (feat. Alesso), I will have a duplicate of the same song in the Singles folder for each Artist, one in the Maroon 5 and one in the Alesso Singles folders
I don't always keep a duplicate file based on all of the featured artists of each song (of all the names that appear in the artist field) - it depends on the "importance" of the artists involved. In many occasions, in the artist field there are several artists that I don't want to be displayed when using a filter, like the artist filter
For example, if there is a song,
Audien - Hot Water (feat. Victoria Zaro)
the tag fields would be
artist field: Audien; Victoria Zaro
album artist: Audien;
Then I will only keep one copy of the song in the Audien, Singles folder. If I filter by artist, then Victoria Zaro will also appear as an artist which is something I don't want.
The only way I can think of as of now to avoid duplicating songs is to have a list of the artists (i.e. in a txt file) that I want to be displayed. Then filter in musicbee by artist (not album artist) but exclude displaying artists that don't appear in the txt file. The txt file is just a guidance, I tried to use a list of artists that I want to be displayed in an autoplaylist condition but I haven't managed so far to show only the names from the artist field that I want to display and exclude the rest.
