MusicBrainz add release not working

I am trying to add an album, but it continuously says “You must enter a title and select an artist for every track.”

You need to turn the “Artist” for each row green by linking each artist to an artist record in MusicBrainz. You can do this by clicking the magnifying glass to open the lookup / editing frame. I can understand your confusion, because this isn’t clear (at least to me) in the How to add a release documentation.


For tracks 4, 7 & 8 you prolly lack featuring artist, press Edit, it will open a dialog where you can enter all artists.
