A way to check which albums I own that Tidal or Qobuz does not have

Sorry if this is not the right place to ask this, and apologies if the topic does not make sense.

I am trying to find out what albums I have in my library that Tidal and/or Qobuz does not have. I am aware of the “Versions” where you can check if a specific album has copies on Qobuz or Tidal. But I don’t want to check every album one by one. I would like to have a number if possible. I checked “Focus” for that, but I could not find what I was looking for. Or does this just not exist?

Thank you for all your help!

You should be able to do this with Soundiiz.

Thank you. How on Soundiiz?

You can do this from Roon now… Go to My Library > Albums and press CTRL-A. Then click on the ellipsis and Export.

Doing this from Souniiz also works, but it’s a premium feature, and IIRC it was the only way to do this when I last tried.

Martin is likely correct, but i think there will be discrepancies if you have unidentified albums? And almost everyone does, right?
