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 has a Bayesian average rating of 72.0/100, a mean average of 69.4/100, and a trimmed mean (excluding outliers) of 69.4/100. The standard deviation for this track is 18.9.

Even the crazy laughter with which Ozzy helped color the atmosphere at the time is a faint copy. So sad.
The laughing is by Ray Gillen, who first sang this songs, before Tony Martin redid them.

A lot of hard work happens in the background to keep BEA running, and it's especially difficult to do this when we can't pay our hosting fees :(
