Since you talk about Picard and "feat." tagging, I was wondering about this the other day. I use Title Case plugin (capitalizes first letter of every word) and was thinking if there is a way to make all of the join phrases (feat., vs., with, a) lowercase. This is hard to do if your join phrases consist of regular words like "with" which you want to be capitalized elsewhere (you would need to do a comparison to album artist or something similar). My question is, how are the join phrases treated currently? Are they simply a part of the title/artist in Picard? What if they had a separate (field? property?) so you could manipulate with stuff like "feat." variations pretty easily.
