Rating metrics:
Outliers can be removed when calculating a mean average to dampen the effects of ratings outside the normal distribution. This figure is provided as the trimmed mean. A high standard deviation can be legitimate, but can sometimes indicate 'gaming' is occurring. Consider a simplified example* of an item receiving ratings of 100, 50, & 0. The mean average rating would be 50. However, ratings of 55, 50 & 45 could also result in the same average. The second average might be more trusted because there is more consensus around a particular rating (a lower deviation).
(*In practice, some tracks can have several thousand ratings)
This track is rated in the top 5% of all tracks on BestEverAlbums.com. This track has a Bayesian average rating of 81.0/100, a mean average of 85.0/100, and a trimmed mean (excluding outliers) of 85.0/100. The standard deviation for this track is 10.0.

I didn't realize this song was so heavy until I heard Randy play it live! The dramatic intro from a classical song that I don't know the name of is a really nice touch for an Ozzy Osbourne show.
