so, I've rated most of my library, but some of the songs either I rated too long ago and my opinion has changed, or they were mis-rated in the first place, so I have 2 spl's for this
1: too high?
rating is more than 3
last played is not in the last month
play count less than 2
2: too low?
rating is less than 4
playlist is top 100 most played
