Along with the YWF example I gave above I just searched Boliden and get the titles in Tidal but it does not show what’s in library. If I drill down from an album in my library it doesn’t show the Tidal contents.
There are so many quirky things like that I’m finding, the search so far in Roon is awful, about the worst I’ve experienced in any music library software. If I search Perila it takes sorting through a lot of artists before I find the one I’m looking for and then the releases shown do not include albums she’s on with other artists I assume because they are tagged “Perila and Ulla” so it doesn’t recognize them as 2 separate artists. Related, Ulla also goes by Ulla Straus (among other alias’s) so it’s a scavenger hunt trying to see all of their releases on one page (despite all being in the same folder in my library). I could go on and on…
