ListenBrainz error: MBID format invalid. (400)
- 
What does this mean? How can I fix it?
 - 
It's a MusicBrainz identifier: https://musicbrainz.org/doc/MusicBrainz_Identifier
Strawberry reads this and uses instead artst, album, track, etc when sending scrobbles to ListenBrainz. (https://picard-docs.musicbrainz.org/en/variables/tags_basic.html)
I suggest to use a tag editor like KID3 or EasyTag and check the MBID's for the specific song.

@jonas Thanks; I'll try to redo the tags with EasyTag
