Ok, thanks for adding to Mantis!
It'd be so simple and smooth to just use album:-live (actually, I use "lv" as
live indicator but same principle. I just wanted
to relate it to what most people do with live)
I'll have to try it later, though. I don't have it in front of me right now.
Just to be clear on the logic,
ex. #0
The example you had before with the vowels, is that to say since some form of positive is needed,
those letters are a good "generic" one, being most common and likely to show up somewhere"?
ex. #1
Again, unfortunately a positive is needed, so if your albums "happen" to not have a rating or one of "0", you could try that as a generic?
...and if not, try something else similar in principle?
Is that the logic of the positives in your examples?
