I think this feature would be very important for the ListenBrainz scrobbler, as it enables a very important feature: Unambiguous scrobbles.

It's the one thing ListenBrainz does better than Last.FM and it's the one feature I looked forward to testing on Strawberry. It didn't support it though, which makes me sad.

Those are the tags as found in MP3 and FLAC files.
There's some more in-depth combinations on Kodi's wiki:

I don't know which IDs ListenBrainz takes though.

Should I open an issue?
