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 3% of all tracks on BestEverAlbums.com. This track has a Bayesian average rating of 81.8/100, a mean average of 82.5/100, and a trimmed mean (excluding outliers) of 82.5/100. The standard deviation for this track is 10.9.

Definitely PJ's best song of the 21st century. An amazing song, and one of Eddie's most touching deliveries

Amazing vocal performance by a quintessential rock voice. A top-shelf Pearl jam song.
Very nice song
