No, just sharing their libraries with you.
And maybe a metadata refresh within the last few months.
But of course, the affected artist must have ‘Similar Artists’, of which some need to be present on your friend’s servers.
Edit the artist and inspect the names under ‘Similar Artists’, on the ‘Tags’ tab.
Maybe your own library also needs a metadata refresh.
I you haven’t refreshed some of your artists in a very long time, they might not even have the necessary metadata attached to them.
