Scanning this fabulous site it becomes apparent that there are many different tastes in Prog music (what exactly "Prog Music" is, is another hotly contested debate altogether).
Some feel that Prog music should not be easily accessible, that it should not appeal to the masses, not be popular at all (High Prog/Low Pop). Others like their music to be progressive, but easily acessible at the same time (High Prog/High Pop). Still others want their music to be accesible and predictable (Low Prog/High Pop). And then there are those who don't like either Prog or Pop (Low Prog/Low Pop).
Using these differing musical tastes as boundaries for the whole Prog/Pop spectrum (and yes, this is a gross oversimplification) I came up with the nine musical varieties as listed in the poll above. In order to more clearly define the nine categories (more clearly, not more exactly), I used Genesis albums as examples of the nine points on the spectrum (fully expecting some debate regarding my choices, and admitting some might not be in the right category).
Where does your musical taste fit in?
