Hold on, I was choosing "GRP1" as the criteria tag for the autoplaylist instead of "Grouping", as they are both in the list of available tags, only because I had an old residue "GRP1" custom tag still there from when i tried defining it as a Custom tag... when I switched it to "Grouping", it started getting hits on autoplaylist criteria. And it was showing up the whole time under the "Grouping" tag in the "Edit tags" window, again i was mistakenly looking at the old residue "grp1" custom tag. I think it's working fine after all, Thanks so much for making this happen!
