I think an important question to ask going forward is how we are defining Patreon exclusive tracks since Ren seems to have moved away from using the Patreon Exclusive Series as an albumfor them. I've personally thought of Exclusive Tracks as the ones that have built in art and metadata, if not flat-out calling it an exclusive. This allowed "The Librarian" and "Just Hesitation (HES3 Edit)" to still qualify in that category.
But I've seen wiki articles saying that tracks like "Tricks & Traps & Twists & Turns" and "fade together peacefully" are exclusives, when the first was just thrown onto the Patreon like any other scribble with just a title and "fade together peacefully" was flat-out stated to be a part of an upcoming project.
Basically I think it'd be best to have a solid definition for these things.
