Progulus Radio Average Ratings by Genre Tag

Without further ado, here's a graph of z-scores by genre tag:

ratings by genre z-scores

Notes on the graph:

Z-scores measure how many standard deviations each item is away from the mean.

Genre tags are not usually exclusive genres, but tags used to try and describe the music. One artist may have several genre tags. For example:

Arena: Neo-Prog, Progressive Rock, Symphonic
Cosmosquad: Heavy Prog-Fusion, Guitar Oriented Rock, Technical, Instrumental
Epica: Progressive Metal, Symphonic, Goth Doom, Female Fronted
John Petrucci: Guitar Oriented Metal, Shred, Instrumental, LTE/Planet X and Influenced, Technical DTI

There are a few catch-all tags that apply to most bands on progulus: Progressive Rock, Progressive Metal, Symphonic, and Instrumental. For instance most Neo-Prog bands are also tagged as Progressive Rock. These super-genres shouldn't be compared with other genre tags due to their breadth, but could be compared against eachother.

Technical DTI is an abbreviation for "Dream Theater Influenced", and also includes Dream Theater and its side-projects. Some other examples include Andromeda, Dreamscape, Spheric Universe Experience.

Fore the tag "LTE/Planet X and Influenced," LTE is an abbreviation of Liquid Tension Experiment.

There are many more genre tags than are highlighted here, but I picked out the ones with the largest pool of data.

"Mean" is obviously not a genre tag, but a placeholder for the average rating.
