it feels for me that the lastfm importer only cares about the artist + title. and totally ignores the album title.
for instance i have played the album Release “Live in the Mojave Desert, Vol. 2” by Nebula - MusicBrainz
and if i inspect the listen i can see that in the additional_info is the mbid of the correct release.
but i guess thats not what listenbrainz is using. the release_mbid in the mbid_mapping is a totally different release.

if i check last fm it all looks good
but in listenbrainz only the title is correct, but the release is incorrect
