Yip, never heard of the other one till Roon assigned albums to him.
@dylan This is an area where Roon’s album ingestion logic could be improved. Before posting the above screenshots I moved all Jack Hammer albums to a folder Roon doesn’t monitor, ran a library cleanup to remove all traces of these albums and restarted Roon. Thereafter I added one album at a time to see what decisions Roon was making. The first album I added was one Roon correctly identified and assigned to the correct Jack Hammer. The second was Unidentified and assigned to the incorrect Jack Hammer. There was more than enough performer, composer and personnel metadata in the Unidentified album for Roon to be able to infer that it’s the same Jack Hammer as the one that already exists in my library. Roon appears to completely ignore this file level metadata when trying to figure out what to do with an album it is unable to identify. I’ve seen this exact same behaviour before with an artist called Karma. I guess this post could be seen as a bug report/ enhancement request.
Thanks for the additional testing here. Would you mind sending the first and second albums that you mentioned above in a PM? I’d like to get them over to our technical team so they can take a closer look at this.
I merged the artists, selecting the correct Jack Hammer as the target. That worked for a while till I added the other albums and Roon decided it knew better and reassigned the lot to the incorrect Jack Hammer and in the process making the correct one invisible
Thanks for the update, @evand. I’ve updated my ticket to the technical team to reflect this new information. This is still in their queue to be investigated but once they get back to me I’ll be sure to update you here.
I moved all the albums to a folder within Roon’s folder tree named ".z ". I also have three compilation albums with tracks by the same Jack Hammer - I moved these to a “.z” folder too (which I’d not done previously when I reported the issue).
I then ran a library cleanup, following which I restarted Roon to ensure there’s nothing hanging around in an uncleared object / variable etc. and then moved one album back into the regular folder tree making the album visible again. Here’s the end result:
As you can see, despite the album being recognised by Roon, it’s still assigned to Jack Hammer AKA Earl Burroughs.
No idea why the behaviour would be any different on your side?
Interestingly the band artwork you see in the first screenshot is something I assigned to the correct Jack Hammer when I’d merged the two Jack Hammer artists, selecting the correct one as the Jack Hammer to merge into.
It seems to me there are update issues/ omissions in the Roon code pertaining to keeping the database current and getting rid of crud e.g. data pertaining to artists that no longer exist in a user’s library.
I had a chat with the team about their findings here. We’ve tried a few different ways but, so far, we haven’t been able to reproduce this behavior on our end. We are thinking there may be specific data existing in your database that we don’t have that is causing this behavior to occur on your end. We are continuing to look into this, but so far we haven’t had any luck.
If possible, it would be interesting to know if you see this same behavior when using a fresh database.
In the meantime, we recommend using the manual identification process.
@dylan I’ve now moved all compositions by Earl Burrroughs out of my collection. I’m going to run a database cleanup and tonight reintroduce Jack Hammer (not the Earl Burroughs version) and see what happens.
Post library cleanup Burroughs still exists in the database despite no compositions or tracks:
I’ve now added Jack Hammer albums to a fresh database and the Earl Burroughs conflation has disappeared, confirming for me that Roon’s database cleanup leaves unassigned objects behind rather than removes them. Seems like a bug fix is required here.
In the meantime I’d appreciate some guidance re the manual identification process you’ve referred to which will result in the correct Jack Hammer being assigned to the Jack Hammer albums in my library.
