This is almost exactly what Christina said happened during Burlesque.
She found the work in the film to directly affect and deter the sound of her new album (Bionic) she felt the need to appease the masses, her original ideas of working with Ladytrong and Goldfrapp fell to the wayside to make room for 'bangers' that people would enjoy like Not Myself Tonight, Desnudate, Woohoo, etc.
Like the thing is, Just Dance was so extraordinary at the time because she really lifted electro-pop and brought it to light. Now that we look back at it, it seems basic because everyone jumped on the bandwagon, but at the time, it was nowhere near basic.
What's wrong with her statement? All pop stars wants to give the public what they want because all pop stars usually want to continue being pop stars having a few public friendly tracks isn't bad nor do I consider it "selling out" (she's already in pop music though...) it's just being logical
I'm concerned for some of you after going through this read and seeing the lack of reading comprehension. The education system has failed you! Read what she's actually saying here.
