I recently added a couple releases (below) from patron-only Patreon posts. I'd like to link them to their Patreon posts, but none of the current relationships seem quite right. A new "download with a paid subscription" relationship would work, or unifying the existing relationships into something like "download/stream for free/subscription/paid" would also work.

There was some discussion at https://chatlogs.metabrainz.org/brainzbot/musicbrainz/2019-11-19/?msg=4485868&page=1 and idea of unifying the relationships was
