Solved Myself...feel free to offer a better solution!
Some have helped me get quite far on my Incorrect Rating playlist but it still isn't perfect. Here is the main query I use:
[=isequal([Ben's Rating],[rating])]=0
The point of this smartlist is to list all songs (audio) where Rating isNOT equal to Ben's Rating
WHERE Rating != Ben's Rating
So this isequal=0 should work, right? Well, the problem is the base starting values. Rating defaults to "?" while Ben's Rating defaults to "". This means that basically ALL songs get returned because "?" != "". So I've been trying a lot of solution techniques but nothing has worked yet. Any ideas?
I used to create this smartlist with a long list of:
(Ben's Rating = 5 Rating != 5) ... 10 times, for all the combinations. But, "OR" seems to be broken in the new Wizard smartlist creator so this broke. I would rather use the clean approach, though: Rating != Ben's Rating! Thanks!
