Pop may be, by definition, intended for accessible, and thus popular audiences, but making doubling up on pop research could make it more appealing to more subcultures. Most other genres are too masochistic in their own way to be appealing to other subcultures, but pop is admittedly, one of the few genres that has the potential to appeal to even the most elitist music-lovers. The method of reaching the upper echelons of masochists is to distill pop to five sigma, a physics term for five standard deviations away from a base measurement, which meets some of the strictest criteria for virtually any musical genre. Naturally, this includes metal lovers, industrial/prog rock, hip hop, and even classical.
Update: Was there a primary reason that caused me to write this post? Yes. I was listening to Vengaboys (Party Album). Europop.
