If you search via the vendor apps for Qobuz, Tidal or Spotify it is easy to find the “Raw Sessions” versions of Queen’s We Will Rock You and We Are The Champions tracks.
Although logged into Qobuz via Roon, I could not get a match on “raw sessions”.
I searched via the Qobuz app, found the tracks and added to my library. I then found them in my library via Roon, and it turns out that in Roon, the tracks are incorrectly labelled “alternative version”, which explains why I could not get a match.
The album art for the tracks gives a clue as to the correct title (screenshot shows that Roon has the incorrect title, no editing on my part).
