Introverted perceiving (Pi) defines the worldview. Our expectation of "how the world works" is based on Ni/Si. Si believes that the future will be pretty much like the past. Ni is transformative - technology (Te) and society (Fe) can be shaped independently of traditional paradigms.

Back to the question of inferior Ni and pop culture. There are 2 ways of looking at mainstream entertainment. The Si version looks to the past - traditional country music, nostalgic themes in movies/tv, etc. Contemporary Christian music is largely an attempt to repackage Si values for a youthful audience.

"Pop culture" values novelty. The emphasis is on the immediate sensory experience (Se). Since extroverted perceiving must be balanced with the opposite introverted P-function then inferior Ni is absolutely associated with trendy, "American Idol" culture.
While I'm not convinced you can map music genre preferences so explicitly, love your analytics from a logical perspective!
