I give my best tracks in all categories except Jazz and classical 5 stars. My best jazz tracks have three stars and my best classical tracks one star.
Why bother to rate so tightly, either you love them or you don't. I tend to make playlists of just 5 stars or just 3 stars. But, if I want to include both- I set it greater than 2 stars.
Thinking of odd playlists, I came up with the idea of a list consisting of:
Match all of the following conditions:
Track Number - is - 2
My Rating - is greater than - 2
Just a bunch of songs with nothing in common but the fact that they're the second song on the album. A baby bit of true randomness for you. [I only picked the number 2 in honor of Blur's brilliant "Song 2"]. Oh yeah, and the rating is just cause songs I don't really like, but are there for the continuity of a whole album are rated 2 stars.
