I think I have complained about this is the far off past, that is multiple copies of the same track in the Pupular by artist, which makes playing these quite a pain and therefor the functionality quite useless (for me anyway).
I see to re remember being told by @mike at the time that it was nigh on impossible to differentiate between a popular track appearing from different sources.
So for Brenda Lee I get 4 versions of Rockin’ around the Christmas Tree in 20 tracks.
So I put these in a playlist and lo and behold Roon’s spots that there are duplicates!
It might be an idea to run this “improver” functionality against Roon’s own suggestions as well as our playlists!
PS I love Roon, it’s just there are a few little annoying things that I’m sure no-one in Roon would stand over that are allowed let fester.
