OKTrends has an amusing post, but what I like about it is that it's consilient with the process I defined here. My idea was that songs that were rated 5 might be good, but might also just be violently weird to the reviewer. By the same logic, the same must be true of the 1s. Assuming that my tastes aren't the same as the reviewer, the information in the reviews was whether the music was either mediocre, or potentially interesting. The output is here.
The OKTrends people seem to have rediscovered the idea independently looking at dating profiles - it's better to be ugly to some and beautiful to others than it is to be boringly acceptable to everybody.
