Hello Tony, and welcome. You noted:
This is very true, Danny Dulai, the COO of Roon Labs, has said that “Roon is very opinionated software”.
In the Import settings of Roon (Settings > Library > Import settings) you can elect to prefer your file metadata tags over what Roon knows, but Roon does have the habit of filling in extra data that it knows about releases. The only way to stop this I think is to force Roon to forget about the album and make it unidentified, but then you will lose a lot of the richness of Roon’s knowledge.
