There are different aspects to consider here:
If there is a Wikipedia page for the specific artist or album, it should be display in Roon. If it isn’t, this would be a bug and should be reported as a bug in Support. Therefore, it would be helpful if you pointed to specific pages that are missing in Roon, so that other users can check this first.
Roon also has artists’ personal websites and accounts on Facebook, X (Twitter), and instagram, such as here:
Therefore, personal websites like the one by Kristóf Bacsó that you posted, https://www.kristofbacsomusic.com/, should arguably be included on Kristóf Bacsó’s artist page in Roon. However, I think they must be maintained by some metadata service that Roon uses. This is probably necessary because not every artist website has an obvious name that can be automatically mapped to an artist.
Therefore, they are often missing for smaller artists. This is not an easy problem to solve because that state of metadata is globally not great (and this is largely the fault of the labels who don’t provide it to the services).
Another problem that is related to the often poor state of metadata in general is that different artists with the same name may incorrectly be mixed up, or that artists exist more than once, with some albums assigned to one version and others to another. This seems to be the case for Kristóf Bacsó, for instance:
In such cases, you can merge them in Roon:
- Add at least one album by each artist to the library
- Select both artists at the same time
- Click the merge button that will appear top right. Note that you will merge one artist into the other, and only the metadata of the artist you “merge into” will “survive”, so choose the better one. You can always undo this merge again in Roon > Settings > Library.
The metadata sources that Roon uses are:
- MuscBrainz
- TiVo / Allmusic
On MusicBrainz, volunteers are doing their best, while TiVo is commercial. However, given that there are tens of millions of small artists and hundreds of millions of small releases, this will never be complete.
I don’t think it’s possible that Roon goes out to search the Internet algorithmically because it’s really difficult to confirm authoritative sources automatically (as opposed to fan sites, etc)..
There are already various feature requests for improvements you can vote for, but this is not always easy. For instance, Bandcamp and Discogs don’t have stable data models that lend themselves well to automation.
It would also be nice if there was an option to add one’s own links, notes, etc:
