Well, in the past people who wanted to create music had to actually have something to say. They were (a lot of the time, not always) professionals, with decades of experience not just in music, but in life in general. When I look at the 80s-90s and the electronic genre, I see people like Jean Michel Jarre, or Mike Oldfield, or even Moby. They didn't sing at all, but they still created music that was a genuine experience.
The best music comes from a place of longing, nostalgia, even melancholy. What longing can be had by a 20 year old "professional singer" who only transfered into music industry at 15, after a failed movie career as a child actress? Her talent isn't music, it's her looks. Which oddly enough fits with the general theme of over-sexualization of everything in the west. Someone really took the idea of "sex sells" to heart, and stuffed it into everything, especially pop culture. If it's a nearly naked, hot, silicone-filled 20-something chick, she could be singing about anything, people would still watch it.
