Script Summary: Adds Taste-o-Meter to artist pages
This adds a Taste-o-Meter like the one on user pages onto artist pages.
This calculates a score for the artist based on a comparison between your top artists and the similar artists of the artist. The presence of the artist itself in your top artists also influences the score (with a greater rating than similar artists).
Unfortunately the scores can sometimes be inaccurate. To improve this it calculates two scores, one using your overall and the other your 6 month top artists. The final score used for the Taste-o-Meter is the average of the two.
