I know that in the musicbrainz datadump that some listenbrainz recording msids are linked to mbids. But the file was lasted updated in 2020. Does anyone know why they stopped updating, or if they still update but somewhere other than the musicbrainz datadump
There are ListenBrainz PostgreSQL Data Dumps. Are they perhaps what you want?
Yes I have checked, but a very small fraction of listens in that dump are linked to musicbrainz mbids.
