Kinda like @61C7hFxpxjQB, I just fly with common sense. That usually works. But now and then a pendant will jump on you with their variation of the guidelines.
There are so many little holes in the guidelines that it is tricky to keep everyone happy. Too many items are decided in the forum but not updated in the official guidelines. It is hard to keep up. As long as you do a good representation of the text, you’ll be fine. Someone will soon come along and correct it if they don’t like it
In this example I would call the Release “Building Sequential Stones, Ecclesias Cathedrales Aedificans, Vol. 1” because that is what is on the cover of the CD, and it is also how it is being described in the text on the band camp page. Remember to add the comma in front of Vol to keep to another guideline.
