The delusion in this thread is real.
I am shocked by amount of people who honestly believe that commercial success can put musician on the top of pop-world.
Katy Perry is a good bubblegum-pop-star who writes safe not risky primitive gp-friendly music without musical or lyrical depth ( musical depth is brave experiments ,lyrical depth is using not banal metaphors and cultural references ).
Perry is successful , yes,but not because she is real artist with interesting vision ,it`s because her images and creativity always relate to the casual listener/ average person who almost always prefers good-sounding/good-looking artistic emptiness than risky,weird ( in vanguard way ),visionary,quintessential pop-reality that Lady Gaga creates
