this is an idea I'd thought of a while ago, but this forum thread reminded me of it

it'd be nice to be able to denote one link as a primary if an artist has multiple links on the same platform, i.e. multiple YouTube channels, Twitter accounts, maybe even official homepages

this would be beneficial to data consumers as if they only show one URL of each type (Twitter, YouTube, etc.) they can easily know which one to show. I believe Google does this, as well as Last.FM, as shown in the forum thread. ListenBrainz might also do this, but I'm less certain of that

I think the checkbox should only be shown if there are multiple non-ended URLs of the same type and service, that way it's not improperly used like the primary alias checkbox has been used in the past
