Edit: Please see the official AutoRate product page for the latest version
I’ve released version 1.4.1 of AutoRate, which now has the option to use just play counts to generate ratings, or a variable mixture of play counts and play frequencies.
As the use of play frequencies tends to bias towards new tracks (which have a high play average, as the track age is small), and the use of play counts tends to bias towards older tracks (which will have a higher play count because they are older), I’m hoping a combination of both techniques may lead towards fairer rating.
There’re also a few tweaks to the way that track skips are factored in to the rating, and the option to select how much effect the previous track rating has on the new rating.
