I organize my songs with multiple artist with the standard "; " separator, and in File Explorer you can just right click and group by "Contributing Artist". This method works in File Explorer, and it translates well when opening the file on MusicBee & iTunes. The files that behave properly are obtained via spoti ripper, and has a ID3v2.4.
However, since I started downloading files via Deemix, the Contributing Artist doesn't translate "; " separator into "/" which it should do. I noticed that the tags are ID3v2.3 so I tried to change that to ID3v2.4 via Mp3Tag. The results are the same. I still get (Eminem; JuiceWRLD) instead of (Eminem/JuiceWRLD) like it should.
Does anybody have the explaination? This is driving me nuts.
