Probably one for a feature request,
But I wonder if a neat and centralised solution to this would be for Roon to create a link to a Roon hosted webpage (ie. share.roon.com/34554) that listed the album/track along with a list of links to open it in each the major streaming platforms.
All the major streaming services have APIs to perform track/album lookups against by name and the results could easily be cached on the Roon servers if desired.
You could then simply share that page with your friends. Free advertising for Roon too if the page containing the links was branded.
