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 61.3/100, a mean average of 59.5/100, and a trimmed mean (excluding outliers) of 59.5/100. The standard deviation for this track is 26.4.

Dude this hook is INSANE. Harmless party pop but it BOPS.
There's nothing profound or special about this song, and it's not trying to be. It's just pure fun. Also, an awesome saxophone solo is always a plus.

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 :(
