Adjusting the Album Formula

In trying to figure out a good formula for ranking my albums I wanted to balance between the average rating of each song, the number of times I’ve played it, and the sum of all the ratings in the album. The first thing I did was throw out any mixes like my Beck Random Stuff mix, which isn’t really an album. Next, I eliminated any albums with less than 7 songs, which were mostly singles or individual tracks.

I weighted the three categories as follows:
Avg Rating: 70%
Play Count: 15%
Sum of Ratings: 15%

Getting an average rating score was easy since it’s always on a 0-5 scale. The others were more difficult. I took the max value for play count and rating sum and made the scale from 0 to that number.

Anyway, here is a chart with the top 100 results.

  1. So I found the other person who bought a Johnny Bravo CD!

    I’ll have to try out the script on my iTunes Lib.
