I once thought that they would be useful, but no longer. There is a serious flaw in the concept.
The problem is that a Popularimeter rating is a relative judgment that has value only at the time that it was made.
Years later almost all of my ratings are grossly obsolete. Sometimes because my tastes have changed. Sometimes because I acquired other versions of a song that I prefer. Sometimes I tire of certain recordings that I played too often. But my Popularimeter ratings are frozen in time.
Reviewing some of my old ratings, I was astonished to discover that today I would give every single recording a different rating (mostly lower). However, on reflection this makes sense. My known "universe" of recordings is much larger now, my tastes have evolved, and my collection has grown.
Users may want to reconsider spending time on these ratings, unless they are willing to update them often. I myself have no interest in tackling that chore.
