Question

I have an music items that are scored by users between 1 to 5, and I need a formula to get the 5 most scored items.

But obviously an item that get 3.5 average score

Answer 1

The term for this is bayesian estimate.

One common example:

Bayesian rating = (v*R + m*C)/(v+m)
where:
R = average rating of song
v = number of votes for the song
m = minimum votes required to be listed (ex. 10)
C = average vote across all songs
