So about the new "multiartist" function:
1.Apps combine artists from vorbis tags into one
2.The spliting "albumartist" in the menu does not work. The first tag is shown, the second is ignored.
3.In the menu / album artists / * artist * / * album * / Duplicating tracks or none at all
4. If "album artist" is one, then the traks are duplicated, if more tracks are missing
5. Tracks with a split symbol are duplicated
Apologies for the sharpness. Maybe in the beginning it is worth making support at the standards level? And then we'll discuss additional features of the parser?
Early I was glad, AC\DC is an exception in MediaMonkey. Well, I don't think "/" is used anywhere other than id3.
In my entire shopping history, I've only seen these signs (words):",", "feat.","ft.","w/", "with."
No, I'm saying about the ID3 standard. There is already a separation symbol and it does not interfere with writing AC/DC together. I don't know how to implement it, but I have an example where it is already implemented. Based on your comment, I got the impression that you want to ignore the standard
I also want to remind you that the words "feat." , "ft.", "f.", "f /", "with.", "w /", "mix", "remix" can separate authors which can be in title and artist lines.
As far as I know, some meta tags (APEv2, FLAC) can contain multiple values with the same key. And also since ID3v2.3 it is prescribed to separate artists with a "/".
