[SOLVED] Tagging albums with multiple artists behaving strange.

[Sehnsucht]

The whole field of audio metadata is a dumpster fire IMHO.

There's differences between what various tagging schemes allow, what different tagging editors require a user to do, what actually gets encoded in a file, and what application software (like the various plugins in MPD) do with the result. On the subject of multiple artists have a look at this discussion which is over a decade old.

What is the best program to use with MoOde for tagging on a PC?

I use Mp3Tag which seems to work but I have run into some issues over the years.

TIA

I use EasyTAG.  It's not perfect but I've stuck with it for years now.
