Well I'll have to disagree with you in that my belief is really good pop has to be mediocre otherwise it will alienate its intended demographics for maximum monetary gain - the 14 year old girls & their mothers group. That's what drives pop music sales. They don't dig complexity, they latch on to simple things. While the theme song for 'Frozen' is most definitely a well crafted tune, it's absolutely engineered to not be challenging or revolutionary. Regarding quality, subjectively speaking individual composition/talents/efforts tend to influence one's opinion of the work seen/heard/etc. This is why music does, in some avenues, resemble a competitive avenue in the collection of skills and techniques. For a not-insignificant number of people, Kanye's music is subjectively bad in quality, which is irrespective of popularity.
