Hi @connor Thanks for merging the threads.
I have now submitted the database as you requested.
I havent added many tags in roon, here is a screenshot.
99.99% of my metadata are at file level.Im not keen to do the heavy-handed workaround that you suggested, as this is not sustainable.
I hope Roon devs can get to the bottom of it and provide a fix.
Also please note the wrong artists highlighted in the original image, I corrected it by going to the album and doing a re-scan of the album. Here are more example which should still be present in the database I uploaded
Cheers
